The Government Agency like Municipal Corporation must issue the notices to such buildings/ structures which are having age more than 30 years. Mostly the maintenance is ignored in many structures which may cause some severe problems. Health and performance of buildings also depends on the maintenance of structure which plays a great role. Thus, Structural Audit of such type of buildings is necessary and timely maintenance /repairs also important. This will lead to prolonged life of building and safety of occupants. It also emphasizes on different repairs and retrofitting measures to be used for buildings after structural audit. Structural Audit is an overall health (strength assessment) and performance checkup of a building. It analyzes the strength and then suggests repair and retrofitting for the building to improve the service life of the structure. Enhance the life of the building by suggesting some preventive repairs. An old building with more than 15 years should be selected for structural Audit. And then the test should be performed on structure. Keywords- Structural Audit, Strength assessment, NDT, UPV Test, Rebound Hammer Test

The sequential ground motion effects on the dynamic responses of reinforced concrete containment (RCC) buildings with typical isolators are studied in this paper. Although the base isolation technique is developed to guarantee the security and integrity of RCC buildings under single earthquakes, seismic behavior of base-isolated RCC buildings under sequential ground motions is deficient. Hence, an ensemble of as-recorded sequential ground motions is employed to study the effect of including aftershocks on the seismic evaluation of base-isolated RCC buildings. The results indicate that base isolation can significantly attenuate the earthquake shaking of the RCC building under not only single earthquakes but also seismic sequences. It is also found that the adverse aftershock effect on the RCC can be reduced due to the base isolation applied to the RCC. More importantly, the study indicates that disregarding aftershocks can induce significant underestimation of the isolator displacement for base-isolated RCC buildings.

Abstract: Modern tall buildings have efficient structural systems, and utilize high-strength materials, resulting in reduced building height, and thus, become slenderer and more flexible with low damping. These flexible buildings are very sensitive to wind excitation and earthquake load causing discomfort to the building occupants. Therefore, in order to mitigate such an excitation and to improve the performance of tall buildings against wind loads and earthquake loads, the tube in tube structures and tube frame structures are the innovative and fresh concept in the tubular structures. Generally, tube in tube structures is formed by connecting peripheral frame tube and inner core tube so closely, it is not seen as a solid system but it acts like a solid surface. The total loads acting on the structures to be collectively shared between the inner and outer tubes. The tubed frames Structure are new concept for tall building. In tubed mega frames instead of one central tube several vertical tubes are carrying the lateral loads. a comparative study of tube in tube structures and tubed mega frame system with different building geometry has been done using ETABS software.

India has been facing many disasters since long. Among the entire disasters earthquake is of serious concern to Civil Engineers. Because of collapse of structures subjected to seismic loads many lives were lost because these buildings were not designed for seismic loads. The problem becomes more serious when additional storeys are constructed. In these buildings many of the columns are not safe if the building is analyzed for seismic load. To make the building safe we need to adopt the technique of FRP (Fiber Reinforced Polymer) jacketing. The FRP Jacketing is comparatively better than other retrofitting because no major strengthening of foundation is required in this technique, also original function of the building can be maintained without any major change in the original geometry of the building. The present study is on a four storey building that has been planned in STAAD.ProV8i, considering M30 cement and Fe415 steel bars.

Abstract High rise structures becoming very common everywhere due to scarcity of land and increasing population. Though we have RCC structure system as high-rise buildings, but in RCC buildings due to bulky size of the components of the structure self-weight will be more due to the heavy density of materials. By observing the difficulties and challenges in the field of high-rise structures engineers are using efficient structural system that is Steel Concrete Composite Structure. Composite structure consists composite deck slab, composite beam and composite column. Composite Structure complies of Concrete which is good in compression and structural steel which good in tension and composition of these material makes structure better in ductility which comparatively on higher side than RCC structure. Here G+7 high rise structure is considered for analysis by ETABS software. This paper involves Analysis of Commercial building by Equivalent static method on Composite structure and RCC structure with same plan of building and same design data. The structure is in earthquake zone III and wind speed 44m/s. Analytical comparisons of both Composite and RCC frame based on structural parameters are made with help of graphs and tables. By comparing the results, we found that Steel-Concrete Composite Structures are more desirable than RCC structures.

Progressive collapse starts when any load-carrying elements of the building collapse during extreme loading, such as earthquakes, blasts, or fire. The Precast Steel Reinforced Concrete (PSRC) buildings comprise of precast RCC columns and steel girders. These structural elements are connected to form a moment-resisting frame and are susceptible to progressive collapse. However, this structural system has the advantage of inherent stiffness and damping during lateral loads and is also known for its construction efficiency, lightweight and low cost. Earlier investigations have shown PSRC systems useful in designing and constructing buildings while maintaining ample strength and high ductility during seismic incidents. Despite much previous research, the PSRC structural system's use is limited in high seismic regions. This paper aims to study the progressive collapse of the PSRC building using non-linear dynamic analysis and U.S. General Service Administration (GSA) guidelines during extreme loading. Two structures are studied to validate the performance of progressive collapse of PSRC and RCC structures. Four-story PSRC and RCC buildings are designed according to Indian Codes of practice. Design columns under provisions of the Indian reinforced concrete structures code, and beams are designed according to the Indian steel construction code. Comparative studies of progressive collapse for the two buildings are presented.

Concrete is good in compression and weak in tension and the steel is strong in tension. So the use of reinforced concrete to resist compression and to hold bars in position and to the steel resist tension. In India RCC structures are commonly used in residential as well as business buildings. Nowadays the Post Tensioning method is widely used due to its advantages. Post tensioning is a form of prestressing, that means the steel is stressed before the concrete has to support the service loads. In this paper is exposed to the assessment of execution of Reinforced concrete beam (RCC beam) and Post-Tensioning beam (PT beam) multistoried building structure framework with seismic load using ETABS software. And also evaluate the performance of PT beam under different seismic zone (zone I, zone II) evaluate the performance of PT beam under soil type (medium soil) and compare the performance of RCC deep beam and PT beam with multistory building system with seismic loading performance.

Abstract Recently, the reinforced cement concrete (RCC) frame has been one of the most commonly used structural systems for buildings in the high seismic region due to its inherent earthquake-resistant property. However, there is still a deficiency in understanding the RCC building structural system dynamic behaviour during significant earthquakes. A 1/4th scaled RCC framed building structure has been tested on the shake table in the present study. The response in terms of engineering parameters like natural time period, damping, story acceleration, and damage pattern have been reported. The 1940 EL-Centro (NS component) time history has been used for the study. The failure patterns were observed within the column-beam joints. The difference between the input signal and the output signal has been noted and found to be in good agreement with each other.

In India the enormous loss of life and property perceived in the last couple of decades, attributable to failure of structures instigated by earthquakes. Responsiveness is now being given to the assessment of the sufficiency of strength in framed RCC structures to resist solid ground motions. The seismic reaction of RCC building frame in terms of performance point and the earthquake forces on Reinforced building frame with the help of pushover analysis is carried out in this project. In this method of analysis a model of the building is exposed to a lateral load. Pushover analysis can afford a substantial insight into the weak links in seismic concert of a structure and we can know the weak zones in the structure. In this project effort has been made to investigate the effect of Shear Wall and Structural Wall on lateral displacement and Base Shear in RCC Frames. RCC Frames with G+13 are considered, one with soft storey and other with normal building in L- shape. The pushover analysis of the RCC building frame is carried out by structural analysis and design software ETABS.

The building sector in Bhutan is responsible for 42% of total energy and consumes 242,916 TOE of thermal energy. The maximum thermal energy was used for space heating. As per the studies conducted on the energy efficiency of the buildings in Bhutan, the buildings are found to be the worst performance in terms of thermal and airtightness. Without the proper insulation, lack of choice of the building materials as per the climatic conditions and lacks of awareness in the society about the green building practices has led to poor indoor quality of life. Buildings located inthe high region are found to be uncomfortably cold during winter months.This research focuses on studying the thermal performance of different building typologies. The main findings of this research were on enhancing indoor thermal comfort and reducing heating energy demand by the incorporation of passive measures. The results were achieved by simulating the buildings in EnergyPlus software using the data collected from questionnaires and field surveys. The simulation results showed that among the investigated buildings, a concrete hollow block wall located at Kabesa has the less comfort hour of 15% at the existing condition. When passive interventions were incorporated into the building, the thermal comfort hours were achievable up to 32% with the load reduction potential of 65%.As for the traditional house with the adobe brick wall and timber wall at Changdagang, had more comfort hours than the building located at Kabesa. With the different set of passive intervention, it was found that comfort hour of 38% to 41% and load reduction of 25.9% can be achieved for the building with adobe brick wall and timber wall respectively. Whereas for stone masonry with cement mortar and RCC framed structure located at Begana and Langdru had a thermal comfort hour of more that 30%. However, RCC framed structure was reported to have huge demand for heating energy compared to stone masonry with cement mortar. The passive intervention prepared for RCC and stone masonry had the potential to achieve 41%-57% of thermal comfort hours. The results from all the investigated buildings revealed that the inclusion of passive design could improve indoor thermal comfort and can achieve a reduction in heating energy demand.

Abstract: The present paper shows seismic behavior of building under the action of earthquake load [ bhuj earthquake] by performing time history analysis. Nowadays buildings with shear walls are more popular than buildings without shear wall in earthquake prone areas due to its resistance during earthquake. In this project G+10 RCC building is considered for the structural analysis for zone III and suitable load combination. The purpose of this study is to find the prime location of shear wall and then investigate the effectiveness of best shear wall for the RCC structure. The structure is analyzed for earthquake in the type of structural system using ETABS software. Wall which is mainly designed to resist lateral forces in its own plane is called shear wall Shear wall are mainly flexural membrane which are specially designed to resist lateral forces which are caused by seismic forces and other forces. Shear wall starts from foundation level and should be continuous throughout of the building.

Abstract Symmetric and asymmetric structures behave differently under external loads even though they are of an equal number of stories or equal in dimensions. It is necessary to estimate the dynamic properties of the asymmetric structures carefully to avoid failure. Modal analysis for symmetric and asymmetric multi-storied reinforced concrete (RC) buildings is very essential to assess the dynamic characteristics of the structure. The plan asymmetric buildings with the shift of core from a central position to different positions and vertical asymmetry with the mass variation in vertical direction and setback stories are considered for the present study. Flexural beam elements are modelled to represent the columns. Two translations i.e., longitudinal, and transverse displacements of the building and rotation about the vertical axis of the structure are taken as global degrees of freedom at each node. The distance between the mass center and stiffness centre on each floor is taken as eccentricity. A finite element model is developed using MATLAB code to estimate the natural frequencies. Different RCC structures of 5 to 20-storied buildings are modelled by developing global stiffness and mass matrices based on the member connectivity. Eigen-value technique is used to estimate the natural frequencies. From the study it is observed that the natural period in asymmetric structures is found more than the symmetric building. The structure with setback also showed larger natural period.

The increase in the number of terrorist attacks has shown that the effect of blast loading on structures is a serious matter that should be taken into consideration in the design process. The blast pressure on the structure due to nearby explosion is of very high magnitude and very short duration. Such an impulsive loading requires dynamic time-history analysis. This paper describes the nature of explosion of explosive materials and dynamic pressure developed on the nearby structure in lieu of explosion. Initially, efforts have been made to determine the effect of 1000 kg of C4 explosive material as an equivalent weight of TNT on different surfaces of a building model at a stand-off distance of 22.5m. The intensity of blast load on each surface is analytically determined as a record of pressure time history. Further attempts have been made to determine the effect of distance of blast for the same explosive material on building surfaces at stand-off distance of 10m, 18.5m, 22.5m and 27m. The effect of different explosives, i.e., TNT, C4, RDX and PETN on building surfaces at constant stand-off distance of 22.5m has also been determined. From the analysis, it is observed that the effect of blast load on front and rear surface of the building is critical. For close range explosions, deformations on front surface are more but with increase in stand-off distance, maximum deformations occur in roof surface.

Abstract Structure collapse, on the other hand, is a very complicated phenomenon involving considerable nonlinearity and a variety of mechanical interactions. It should be thoroughly examined through experiments and numerical simulations to prevent the occurrence from occurring. When initial local failure of a small portion of the structure takes place it leads to the spread of that local damage to neighbor elements in the chain reaction manner. Finally, collapse takes place. This is known as Progressive collapse. This progressive collapse takes place when vertical load carrying members such as columns failed due to manmade or natural accidental loads. Therefore in this study progressive collapse analysis of a building is carried by removing columns. In the analysis different column removal cases are considered. As per GSA guidelines, Demand Capacity ratio(DCR) of beams are calculated. From this DCR value Evaluate the stability of the structure against progressive collapse. In the present study “T”shape building is considered which consists of 11 storey with bay sizes as 4 meter in the X and Y direction, height of every storey is 3 meters and height from the plinth to the floor is assumed 3.5 meters. The measurements of the beams are fixed throughout the storey, but column dimensions decrease as the floor rises, therefore the structure is considered to have geometrical irregularity. The loading is calculated in accordance with G.S.A guidelines. The design was created using the ETABS software and the I.S 456-2000 code. Different parameters such as Demand-capacity ratio, Dynamic factor, Interaction ratio, Axial Force, Bending moment are discussed.

Fire in a building is a casual phenomenon but cannot be completely ruled out in spite of the facts that buildings are provided with mandatory fire safety measures. A symmetrical in plan with 5 bays with 20 stories regular RCC building has been considered with fire at three different level that is at the bottom, middle and top. The building has been designed for gravity loads and lateral loads having three different configuration of shear walls and columns. Fire temperature of 700 0C was considered. The minimum value of maximum fire temperature for failure of vertical members has been found out by iterations. The worst verticals members due to fire has been identified and their displacement calculated. Best location of shear walls using commercial software etabs is used for the analysis and design.

The major purpose of this study is to justify construction method of a hybrid structure in core area with construction complexity due unsafe excavation conditions and tries to define its rigidity and strength. Both RCC and Frame structure transfer same load to ground through foundation but the transfer mechanism varies. In some practical condition, building construction should be carried out in compact areas with unsafe adjoining building where adequate excavation for foundation cannot be carried out. In such cases, one bay hybrid structure is proposed for construction with combined RCC frame structure and load bearing walls. In these combined cases, both structures works as same unit to transfer building load but the transfer pattern varies. The variable load transfer pattern is due to discontinuity in structural system which also effect on seismic response of the building. The placement of a masonry load bearing structure in RCC frame structure varies design of all structural components of the building. To study actual behavior of hybrid structure in various load condition and introducing cost minimization techniques of buildings structural analysis was carried using ETABS 2016 with composite structural arrangement and with induction of load bearing wall as structural component. By which seismic behavior of building in both cases was obtained as well as reduction in rebar percentage and dimensional reduction of structural components can be achieved.Journal of the Institute of Engineering, 2017, 13(1): 117-124

Abstract: This study examines the composite structure that is increasing commonly in developing countries. For medium-rise to high-rise building construction, RCC structures is no longer economical due to heavy dead weight, limited span, low natural frequency and hazardous formwork. The majority of commercial buildings are designed and constructed with reinforced concrete, which largely depends on the existence of the constituent materials as well as the quality of the necessary construction skills, and including the usefulness of design standards. Conventional RCC structure is not preferred nowadays for high rise structure. However, composite construction, is a recent development in the construction industry. Concrete-steel composite structures are now very popular due to some outstanding advantages over conventional concrete and steel structures. In the present work, RCC and steel-concrete composite structure are being considered for a Dynamic analysis of a G+25-storey commercial building of uniform and optimized section, located at in seismic zone IV. Response Spectrum analysis method is used to analyze RCC and composite structure, CSI ETABS v19 software is used and various results are compared such as time period, maximum storey displacement, maximum storey stiffness. Maximum storey shear and maximum stoey overturning moment.

RCC framed buildings mainly consists of shear walls and columns for resisting lateral force due to earthquakes. In most of the framed buildings shear walls are provided in the outer frames. In addition to shear walls provided in the outer frames, RCC lift -well (core wall) is also provided in the inner core of the buildings to accommodate lift. Core wall also acts as shear wall contributing to the lateral resistance to the buildings. In the present study, nonlinear static analysis is performed to study the behaviour of high rise RCC buildings, the buildings have a centralised lift core wall with a door opening and shear walls in outer frames.

The present decade, high rise multi-storey buildings are subjected to many external effects such as earthquake, wind loads, tidal loads, etc., in most cases high rise buildings have more vulnerable to earthquake and wind loads. Most of the reinforced concrete multi-storeyed frame buildings were heavily damaged and many of them completely collapsed during due earthquakes. RC frame buildings were severely damaged due to various deficiencies when proper codal provisions are not designed. A study is need to study the behaviour of the RC framed structure under earthquake load to reduce the damage caused by earthquake forces In this investigation a RC framed building of G+20 storeyed is considered in several seismic zones under different soils as per Indian Standard code IS 1893(part1):2016, using STAAD. Pro V8i as software tool. Finally evaluate the ultimate Base shear using Equivalent static method and Response spectrum method addressing under design forces.

Abstract. Dynamic load is one which changes with time quickly in comparison to the structure's natural frequency. If it varies quickly, the activity must be determined with a dynamic analysis. Explosive loads and impact loads are transients, or loads that are applied dynamically as one-half cycle of high amplitude. This transient load is applied only for a specific and typically short period of time in the case of blast loads typically less than one-tenth of a second. The response of the engineering structural building due to the reason of periodic load RCC building structure has been severely damaged, collapse and develop cracks. Bomb blast is the best example for impulsive load. To determine the response of a G+3 RCC building model in STAAD Pro subjected to triangular, rectangular and sinusoidal impulsive force for 0.5 seconds with maximum magnitude of 100kN. Effect of such loads on front, roof and side portion of the building studied. Observe that the critical deformations obtained on the front and roof portion of building. Effect of deformation along height of building was parabolic in nature with maximum deflection at top floor of building. It was also noted i.e sufficient reinforcement should be provided in beam, columns and slabs to impart ductility to the building against impulse loads.There is more demand for construction of high buildings due to increasing urbanization and population.

Civil Engineering Industry is one of the oldest industries which provide a basic infrastructure to all the human beings. Structures can be any kind it can be Historical, Heritage Structure, Residential building, Commercial building or an Industrial building. Every structure has its own service life, and within this service life it should stand firmly on its position. Ex- A Taj Mahal in Agra in India which is one of the oldest structures and a Wonders of the World, and still stand on its position very efficiently. But this not a condition about the today’s Structures. A collapsed mechanism has increased and today’s Structures are getting collapsed before there service life is completed. Therefore, it is advisable to monitor it periodically by taking a professional opinion. Structural Audit is a preliminary technical survey of a building to assess its general health as a civil engineering structure. It is usually initiated as the first step for repair. In this Project a Root Cause of a faulty mechanism of structure and a preventive measure to overcome a failure of this structures. The construction material mainly reinforced concrete is being used extensively for various types of construction projects. However, the deterioration of Reinforced Concrete structures is recognized as a major problem worldwide. Apart from requiring regular maintenance, many structures require extensive Repair, Rehabilitation & Retrofitting. Over a period of time, as these structures become older, we find in them certain degradation or deterioration with resultant distress manifested in the form of cracking, splitting, delaminating, corrosion etc. Such deteriorated structures can be rehabilitated and retrofitted by using various types of admixtures & modern repair materials. The paper brings out the present state of concrete structures & the major areas where improvement is needed during its service life stage for sustainable development & also the method of carrying out Repair, Rehabilitation &Retrofitting. This has been brought in details in the paper along with Case studies, where the Author of the paper was directly involved in planning and execution of the job.

This study deals with the evaluation of the seismic performance of irregular buildings by comparing various seismic responses of six types of building, namely regular building, setback building, stepped building, mass irregular building, stiffness irregular building, and building with floating columns which are constructed of Reinforced Cement Concrete (RCC) subjected to extreme earthquake loads. The nonlinear time history analysis (NTHA) method is carried out to obtain different seismic response parameters for all considered irregular and regular buildings. The structural response results are compared by applying real earthquake records of different near-field and Far-field earthquakes and were compared for four different seismic response parameters which include top storey displacement, inter-storey drift, top base shear, and pattern of plastic hinges formation. This research concludes that the storey displacement, storey drift, and top base shear is significantly less for stepped and setback buildings, and significantly high for mass irregular, stiffness irregular, and floating columns buildings as compared to a regular building. Stepped buildings yield less responses and high responses are yielded in the building with floating columns.

It is very important and necessary to assess the seismic risk for the buildings subjected to uncertain and highly unpredictable dynamic forces produced from earthquakes. Fragility curves are the best tools for the representation of seismic risk assessment. In the present study, risk assessment of structure subjected to seismic loading is evaluated. Further, the effects of different eccentricities are also studied for seismic risk assessment. The fragility curves are developed for G+5 storied RCC bare frame building as well as G+5 storied RCC building with shear wall. The considered buildings are subjected to ground motions of past recorded earthquakes. Buildings with different eccentricities and various structural configurations are studied for various failure criteria. The responses of the considered buildings subjected to earthquake excitations are evaluated by Incremental Dynamic Analyses. Fragility curves are developed using Monte Carlo method considering various performance levels as per ATC-40. It is observed that for immediate occupancy failure criteria, the probability of failure is increased constantly with increasing the percentage of structural eccentricity. Further, it is observed that very less variation is observed in the probability of failure under life safety and collapse prevention failure stages.

Numerous studies have been conducted on high-rise buildings, focusing on various aspects such as construction methods, building materials, and responses to seismic and wind pressures. In this paper, the influence of plan aspect ratio on the behavior of high-rise buildings is examined in detail. According to IS 16700:2017, the plan aspect ratio is limited to 5. However, in this study, the plan aspect ratio has been studied up to 6, and the behavior of high-rise buildings under seismic forces has been investigated. The building model has been constructed in three sets, each with varying heights. Building heights of 10, 20, and 30 stories have been selected for each group of buildings, respectively. For each set, seismic metrics, including ductility, stiffness, and base shear, have been compared, and conclusions have been drawn.

Abstract: The majority of India's hilly regions are prone to earthquakes. A building on a steep slope is distinct from other structures. That is to say, structures that are to be constructed on hilly terrain have a higher risk factor of falling prey to seismic activities as compared to their counterparts built on a rather plainer terrain. The numerous floors/storeys of such a structure step back towards the hill slope, and buildings may also have setbacks. As such, the column of a hill structure sits at different heights on the angle of the terrain; its analysis differs from that of buildings on level ground. The current study looked at G+3 and G+4 structures with different slope angles, such as 00 , 7.50 , 150 , 22.50 , and 300 . Both Step back and Step back & set back types of building configurations have been studied in this paper. The earthquake forces are calculated according to IS: 18932002; the structures are situated in seismic zone IV, with a damping ratio of 5%. Linear Static and Linear Dynamic methods were employed to conduct the seismic study. To investigate the influence of shifting column heights in the ground level due to sloping ground, a 3-dimensional analytical model of building plan was created and the same was studied using the structural analysis application "STAAD.Pro." To quantify the effects of diverse sloping terrain, response parameters like top storey displacement, base shear, shear in bottom storey column, and time period were thoroughly studied. It has been discovered that short columns on the elevated side of the terrain/slope experience a greater shear force as compared to columns of increased height on the lower side of the terrain. Under earthquake stresses, Step back & Setback structures showed better resilience to seismic forces as compared to Step back buildings. Step back setback buildings have substantially lower base shear and top floor displacement than setback buildings on sloping land.

Abstract: As the modern buildings have been getting taller and narrower than before, the structural engineers have to perform both static and dynamic analysis for seismic loads that may affect on structures in order to make sure of the safety verifications and the optimal design requirements. Reinforced concrete (RC) building frames are the most common types of constructions in urban India. Throughout their lifetime, these are subjected to various types of forces such as static forces due to dead loads, live loads and dynamic forces due to earthquakes. In the present study, one tall RCC building of 10 stories is assumed to be situated in seismic zone 4 is analyzed using two different methods i.e., Equivalent static method (static) and response spectrum method (dynamic), using ETABS software. From analysis, the parameters like storey displacement, storey drift, base shear and time period and frequency are determined and also comparative study is done for both the methods Keywords: {RCC Buildings, Equivalent static method, response spectrum method, storey displacement, storey drift, Base shear, time period.}

Research capacity building (RCB) in Australia has recently focussed on strategies that take a whole of system approach to developing research culture at individual, team and organisation levels. Although a theoretical framework exists, no tool has been published that quantitatively measures the effectiveness of RCB interventions aimed at these three levels. A sample of 134 allied health workers was used to validate the research capacity and culture (RCC) tool. Item level analysis was undertaken using Cronbach’s α and exploratory factor analysis, and test–retest reliability was examined using intra-class correlations (ICC). The tool had one factor emerge for each domain, with excellent internal consistency for organisation, team and individual domains (α = 0.95, 0.96 and 0.96 respectively; and factor loadings ranges of 0.58–0.89, 0.65–0.89 and 0.59–0.93 respectively). The overall mean score (total) for each domain was: 5.4 (inter-quartile range 3.9–7.7), 4.4 (IQR 2.6–6.1) and 3.9 (IQR 2.9–6) for the organisation, team and individual domains respectively. Test–retest reliability was strong for each domain: organisation ICC = 0.77, team ICC = 0.83 and individual ICC = 0.82. The RCC tool has three domains measuring research capacity and culture at organisation, team and individual levels. It demonstrates excellent internal consistency and strong test–retest reliability.

Concrete has changed the norms in the Construction industry, it has modified the thinking and possibilities of the general public. Particularly, Reinforced Cement Concrete (RCC) is being used throughout the world; whether it be tall sky scrapers in the Middle East, or the vast buildings in Central Europe, RCC has altered the construction Industry. But then again, RCC has its fair share of shortcomings, in recent times it has been recorded that RCC structures collapse due to brittle failure. Seismic loading, mainly from earthquakes are mostly responsible for structure failure as seismic waves generally lead towards overloading and ultimately the structure fails. Cement is generally an energy releasing material and it releases immense amount of CO2 emissions into the earth’s atmosphere, causing the ozone layer to deplete. Hence to minimize this impact and to provide a sustainable solution and to minimize the accidents different sustainable houses are being provided to the people. By doing this, we can reuse existing building assets to minimize the waste and to reduce the pollution. In 2011, International Organization launched the Life cycle Sustainability assessment to have a more sustainable approach towards construction by using different techniques. Life cycle sustainability assessment is a suitable too used for environmental performance of buildings. In this paper we will look to observe different provisions of sustainability in different structural designs taking different codes as a reference.

Abstract: ETABS Stand for Extended Three-Dimensional Analysis of Building systems. ETABS integrates every aspect of the engineering design process. In the present situations of construction industry, the buildings that are being constructed are gaining significance, in general those with the best possible outcomes which are referred to members like beams and columns in multi storeys R.C structures. This paper deals with the seismic analysis of regular B+G+26 story building with shear wall and G+B+10 Story building with different irregular shapes considering different shapes of shear wall at different locations has been carried out. Which can be done in ETABS taking all the considerations regarding codes and other factors into account. All the buildings were analyzed with the same method as stated in IS 1893-Part-1:2016. The effect of shear walls on lateral capacity of the building are examined because the seismic analysis of a frame depends upon the location and symmetry of shear wall. Present study shows the shear wall improves not only the lateral stiffness and strength capacity but also the displacement capacity of structure. Comparison of results been done of different models by comparing the parameters such as story drift, story displacement, story stiffness and base reaction. Therefore, as far as possible irregularities in a building must be avoided. But, if irregularities have to be introduced for any reason, they must be designed properly following the conditions of IS 13920:1993. The complex shaped buildings are now days getting popular, but they carry a risk of sustaining damages during earthquakes.

Due to rapid urbanization and economic growth there is huge demand for construction of building. Since population density is high it led to construction of buildings on sloping ground, but this sloping grounds like hilly areas are more prone to earthquake which causes severe damage of life and property. The buildings constructed on hilly areas are different from buildings constructed on flat ground buildings on hilly areas have horizontal/plan, vertical, torsional, mass and many more irregularity. The structure irregularities are considered as one of the main fundamentals of its failure. Here we have done seismic analysis of a G+9 regular RCC building, C and I shape building of floor height 3m resting on sloping ground of horizontal angle of inclination 45o on zone II, Response spectrum analysis is done for three cases that is plain building and building with shear wall and bracings for all the three buildings, after analysis the response of the structures with respect to variation in the story drift, story displacement, base shear, story shear has been recorded and will be discussed and concluded.

The present paper focuses on developing a strategy to control the indoor temperature in slum dwellings under redevelopment. The proposed framework aims at improving the building planning and appropriate selection of construction materials along with controlled cost with respect to currently adopted practices. The proposed strategy is elaborated with a case study in Nagpur, India. A single storey, four-room model was planned as per the National Building Code of India. The performance of the model building was evaluated by using energy simulation software TRNSYS. The cellular light-weight bricks used in the construction were made with bio briquette ash (BBA), which is a locally available waste material. Instead of using the conventional reinforced cement concrete (RCC) roof, aluminium and sawdust were suggested as a reflecting-cum-insulating material. To improve the temperature control in model homes, installation of a reflecting-cum-insulating material was conducted, consisting of aluminium and sawdust, over the conventional RCC roof. The model building constructed with these new materials was compared with that built with conventional fly ash bricks and RCC roof. Results show that the proposed model building improved the efficiency of indoor temperature control by 23% and, at the same time, reduced the cost by 13%. The present concept will contribute to the redevelopment of slum dwellings to deliver cost-effective dwelling units that provide occupants with acceptable thermal comfort.
