Abstract:
Abstract: The high-rise building in which ground storey consists of open space is known as building with soft floor. Such floor plays an important role in seismic performance of the building. This is due to the abrupt changes in lateral stiffness and strength caused by such storey. In the present era there is increase in population, finding parking for flats in congested areas has become a significant issue. As a result, erecting multistory structures with an open first floor is now a widespread practice. These Buildings that have all upper storeys enclosed by masonry walls but no infill masonry walls in the ground story are referred to as "Soft Storey" or "Open Ground Storey Buildings." Compared to regular buildings, irregular structures the drift is observed to be effectively reduced by larger columns, while the shear force and bending moment on the first floor are increased. During a violent earthquake, the Soft Storey buildings function poorly. Understanding the behavior of is this study's primary goal to the building in a seismically active area and to assess the effects of Storey overturning moments, Storey drift, displacement, and design Base shear. For comparison, G-15 story building with five completely distinct shapes a square, an L-shaped building, a Tshaped building, a plus shape building and a C-shaped building is used. ETABS 2018 version is used to analyze the entire set of models. Dynamic Analysis has been examined in the current work to assess the deformation of all five-shape building with and without soft storey considering at different level. When the soft story is offered at a higher level, displacement is reduced. Several studies on this subject that have been done in the past are reviewed in this paper. Reviewing research papers let us know about the conclusive results, which served as the basis for the objective of our future study.

Abstract:
Open ground storey or soft storey is a typical feature in multistory structures in urban areas. This open storey is provided to accommodate parking, reception lobbies, office, communication hall etc. Many of structure having soft storey suffered major damage and collapsed in recent earthquakes. During an earthquake, because of variation in stiffness in soft story and its adjacent floors the inter story drift can occur and the lateral forces cannot be well distributed along the height of building. Lateral forces concentrate on soft story causes large displacement. In this work, an attempt has been made to observe the behavior of gradual decrease in stiffness of building, by using different types of infill material. This work discusses Optimum Earthquake response of tall buildings by response spectrum method as per IS 1893:2002 (Part- I) in ETAB’S software. Seismic parameters like storey stiffness and storey displacement are checked out.

Abstract: The Performance of The RCC Building During Earthquake Depends Upon the Distribution of Stiffness Amongst The Storeys. If The Distribution Is Non- Uniform To A Large Extend, The Performance of The Building is Poor. The Storey Stiffness is Contributed By The Columns As Well As The Brick Infill. If The Effective Storey Stiffness of A Floor is Less Than 70% of the Storey Above Or Below It , Then It Is Called The Soft Storey. It Is Learnt From The Past Earthquakes That Soft Storey Are More Vulnerable To Failure. The Study of Building Performance During Past Earthquakes Has Revealed That Maximum Failures Have Occurred In The Parking Storey. Most of the buildings were damaged and collapse during in strong earthquake hence we will have to confirm safety against the earthquake force that are affecting the structure, and determine seismic responses of such building. In this project we will analyse the G+5 building through response spectrum analysis to develop the economic design. Computer software’s are also being used for the calculation of forces, bending moment, stress, strain & deformation or deflection for a complex structural system.

Abstract:
Abstract In this paper (G+8) building is modeled like a bare frame, a bare frame with the shear wall, and a bare frame with X bracing by changing the soft storey to different floors. The static analysis effect is determined for all three models with zone IV and zone V using Staad pro-V8i software. The main objective of the research was to assess the impact of a soft storey in various earthquake zones and by varying places of the soft storey from first to the top floor and for frames with different column shapes by seismic analyses in staad pro. The results of variable building models are obtained from the research regarding various parameters such as displacement, storey drift, and base shear. More significantly, comparing different structural systems revealed a reduction in lateral displacement and story drift. The shear wall reduced the Storey Displacement by 98.838% and storey drift by 99.86%. The Steel bracing reduced the Storey Displacement by 97.846 % and storey drift by 92.6%. Finally, it has been found that the Shear wall reduces lateral displacement and storey drift, thus significantly contributing to greater structural stiffness. The analysis results recommended that the shear wall use reinforced concrete frames for the seismic hazard zones and the Steel bracing recommended for the low seismic zones.

Abstract:
Abstract Vertical structures exhibit flexibility than ordinary structures and also they show sensitivity in earthquake excitation. As per the safety standards of construction, structures are built with simple and uniform configurations. Focusing on aesthetic view of these vertical structures, discontinuity in stiffness occurs there by resulting in soft storey. this feature is highly undesirable in buildings especially in seismic active zones. However soft storey cause large deformations at the junction of building lead a greater failure for life and property. An attempt has been made to predict seismic performance of these structures considering G+ 14 storeys. Developing soft storey at base and mid level of G+14 structure and evaluating its seismic performance under non linear static analysis by using SAP2000. A comparative study is made based on, with and without soft storey of G+14 structure and results are tabulated.

Abstract:
In India, hilly region especially northern part is more seismically active region. Flat Slab systems are widely popular in multi-storey buildings. Flat slab building has more advantages than a regular building like fast construction, free design space, reduced floor to floor height and economical. Flat slab buildings are also being built in high seismicity region. Buildings on hilly ground are vulnerable due to their vertical and horizontal irregularity and they undergo high shear and torsion during the earthquake. Further due to short column and soft storey on uphill side has higher lateral forces that are cause to failure of buildings. In this paper, an attempt has been made to assess the seismic behavior of flat slab resting on hilly slope with soft storey and set back configuration. The methodologies have been adopted are linear dynamic analysis i.e. response spectrum analysis. Building is analyzed and designed by Etabs software. Maximum displacement, maximum inter-storey drift and storey shear are determined as response quantities. It is observed from the study that for flat slab buildings on hill slopes the storey shear is very high in the bottom columns at higher ground level, therefore extra care should be taken to design these columns for earthquake load.

Abstract:
Abstract: Quintuple friction pendulum (QFPS) bearing is a new generation sliding isolation system having multiple spherical sliding surfaces. The friction isolation system with single sliding surface is designed for a specific level of ground shaking, which may prove ineffective in case of other hazard levels. The QFPS bearing on the other hand, exhibits adaptive behavior and imparts greater amount of flexibility to the designer for various levels of earthquake shaking. Here, the effectiveness of Quintuple Friction pendulum system is carried out to study the seismic demands of base-isolated building frames with stiffness irregularities and plan irregularities subjected to various earthquake ground motions i.e. Far field ground motion, near field ground motion with fling step and near field ground motion with forward directivity by comparing their estimates with the benchmark responses obtained by the Non-Linear Time History Analysis (NLTHA). SAP 2000 Software has been used for the same. The two soft storey buildings and two buildings with plan irregularity will be modelled and analyzed. The seismic demands namely, Inter story drift, peak storey acceleration, maximum base shear are considered for the study.The reduction in absolute acceleration is found more in case of PI as compared to SS for all the considered time histories. The reduction in Maximum Base-Shear is found more in case of Plan irregularity as compared to Stiffness Irregularity (Soft Story) in all the considered Time History. In isolated structure, the Inter-storey drift is found to be maximum in case of structure having soft storey as compared to plan irregularity 1 and 2.

Abstract The modern design and construction of buildings have led to the adoption of irregular shapes buildings which can attract large seismic forces and induce stress concentrations in the building itself. To investigate this fact a large number of research studies have been carried out. This study presents a review summary of seismic performance of irregular buildings considering vertical irregularity subjected to earthquake loadings. The seismic performance can be found by using linear and nonlinear time history analysis. Different types of irregular buildings are analyzed to review the seismic performance of the structure. It was found that the buildings with the soft story having variation in the storey stiffness yield large inter-storey drift values showing more damage as compared to types of building irregularities.

Abstract:
Nowadays highly increases in the high rise building with architectural requirement in modern city. The purpose of the study is to understand the response of the building due to vertical irregularities. In this paper the incorporated irregularities are as per IS1893 (Part )1:2016 and study response of 12 story building frame 13 models with mass irregular, stiffness irregular and vertical geometric irregularities are analyze in ETABS 2017 by linear dynamic analysis i.e. Response spectrum Analysis. The various structural response parameters such as maximum storey displacement, inter story drift and storey shear are taken to compare the result. Mass irregularity is placed in fourth story, stiffness irregularity is provided in first storey and vertical geometric irregularity is provided in different upper floor. It is concluded that the soft story at bottom highly increases the lateral displacement of that floor, mass irregular at fourth story highly increases the storey shear below that storey and vertical geometric irregularity effect on the relative displacement of building. Combined irregularity highly effect performance of the building therefore chance of collapse also increases as increases in irregularities. All the comparison are represented graphically.

Abstract:
The infill masonry walls are seldom included in analysis of reinforced concrete structural systems, since masonry panels are generally considered as non-structural components. However, these panels affect the structural response, although the complexity they introduce to analysis. The effects of masonry infill on the global seismic response of reinforced concrete structures arethe part of study. Recently, it becomes important to determine the earthquake behavior of structures with infill walls in earthquake engineering. Parametric analyses on a large variety of multi-storey infill reinforced concrete structures show that, due to the hysteretic energy dissipation in the infill, if the infilling is uniform in all storey, drifts and structural damage are dramatically reduced, without an increase in the seismic force demands. Presence Soft-storey effects due to the absence of infill in the bottom storey in building is a measure problem in earthquake, as soft storey is significantly less strong or more flexible, a large portion of the total building deflection tends to concentrate in that floor with consequent concentration of stress at the second floor connections and in that case collapse is unavoidable. Open first storey is a typical feature in the modern multistory constructions in urban India. Such features are highly undesirable in buildings built in seismically active areas; this has been verified in numerous experiences of strong shaking during the past earthquakes. The present study highlights the seismic performance of RC frame building with soft stories at first as well as at different floor level. A parametric study is performed on an example building with soft storey and it is intended to describe the performance characteristics such as stiffness, shear force, bending moment, drift. The effects of masonry infill and cross bracing on above parameters have been studied for a building with soft storey. The modeling and post-processing is carried out using ANSYS software. The comparisons of different parameter of models have also been presented in the study.

Abstract:
The construction of reinforced concrete buildings with unreinforced infill is common practice even in seismically active country such as Bhutan, which is located in high seismic region of Eastern Himalaya. All buildings constructed prior 1998 were constructed without seismic provisions while those constructed after this period adopted seismic codes of neighbouring country, India. However, the codes have limited information on the design of infilled structures besides having differences in architectural requirements which may compound the structural problems. Although the influence of infill on the reinforced concrete framed structures is known, the present seismic codes do not consider it due to the lack of sufficient information. Time history analyses were performed to study the influence of infill on the performance of concrete framed structures. Important parameters were considered and the results presented in a manner that can be used by practitioners. The results show that the influence of infill on the structural performance is significant. The structural responses such as fundamental period, roof displacement, inter-storey drift ratio, stresses in infill wall and structural member forces of beams and column generally reduce, with incorporation of infill wall. The structures designed and constructed with or without seismic provision perform in a similar manner if the infills of high strength are used.

Abstract:
Soft-floor buildings, characterized by open spaces on the first floor, pose challenges to seismic performance. To address this, braces and shear walls are commonly employed to reduce displacement and improve seismic resilience. Shear walls and braces enhance lateral stiffness, minimize displacement, and ensure safety. This study investigates the seismic response of soft-floor RCC buildings, considering parameters such as soft floor height, shear wall placement, and brace types and arrangements. The goal is to enhance structural safety without extensive alterations. Analysis is conducted in three phases: soft-storey analysis, shear wall implementation, and brace integration. Shear walls are assessed at the center and corners, while different brace arrangements are examined. Results reveal the effectiveness of shear walls in enhancing stiffness and reducing displacement. Incorporating bracing systems improves overall building performance. Cost-effective strategies for strengthening soft-floor structures are identified, with findings summarized based on seismic response.

Abstract:
A high-rise building whose first floor is composed of open spaces is called a soft floor building. Such floors have a substantial impact on a building's seismic performance. this is awing to the floors abrupt lateral stiffness and strength fluctuations. A large earthquake can cause enormous damage or collapse of a building. Previous studies have shown that structure damage from earthquakes is the cause of large displacements. If the structure, is intended for horizontal loads, the structure will show greater deflection. Braces and shear walls are the most common lateral load-bearing systems for reducing displacement. Shear walls and braces are used for improving lateral stiffness, ductility, minimal lateral displacement, and safety. Story drift and lateral displacement are essential considerations in seismic design of structures. shear wall was added inside the proposed structure to counter the lateral load induced by earthquake and to improve structure's stiffness. Therefore, by making use of shear walls in the building, it is possible to prevent large displacements and thus damage due to displacements. In addition, Bracing is also mainly used foe structures exposed to wind and seismic loads. It resists the forces of the bracing element in both compression and tension. As a result, the brace system withstands horizontal loads very efficiently. The brace frame makes the system more efficient and stiffens the structure laterally. By adding material to the bare frame, it forms an efficient structure for higher heights. In this thesis work, the seismic response of soft-floor RCC building is studied using seismic analysis method. the parameters considered in this study include soft floor heights, shear wall position, bracing types and arrangements along the height of the building. Furthermore, the effectiveness of using simple strengthening procedures to increase structural safety will be investigated without causing large changes tot he building's architectural and functional needs will be studied

Abstract:
This research study represents an important contribution towards fulfilling the long-term objective of the research program in terms of assessing and controlling seismic risks of building structures in low and moderate seismic regions such as Australia. The research outcome enables the existing building stock to be assessed in an inexpensive way. Post-disaster agencies and insurance agencies could then better assess risk exposure. The displacement controlled phenomenon associated with conditions in low and moderate seismic regions has become the basis of a new performance assessment methodology for strength degraded structures.
In low and moderate seismic regions the kinetic energy demand generated by a small or medium magnitude earthquake (M<7) (at an epicentral distance consistence with Peak Ground Velocity (PGV) of up to 80 mm/s on rock) will generally subside when the structure has been displaced to the maximum limit. Current design guidelines in seismic design and assessment of structures has been based on trading-off strength with ductility demand to accommodate large displacement without significant strength degradation to ensure that structures have sufficient energy dissipation capacity. The drift capacity recommended for strength degraded structures is quite low as per the current guidelines which are developed for high seismic regions and it is considered that a structure is deemed unsafe when the lateral strength has degraded by more than 20%. An important investigation has been undertaken to determine if such structures are actually unsafe, should the displacement controlled phenomenon be taken into account.
Therefore, the research described in this thesis is aimed at capitalizing the displacement controlled concept (not to be confused with the displacement based design methods) which is particularly relevant for low and moderate seismic regions for investigating the seismic performance of strength degraded structures. If the peak displacement demand (PDD) and the displacement capacity of the structure are known then the displacement based approach can be applied directly for assessing the performance of the structure. The seismic displacement demand is then simply compared with the displacement capacity to ensure that its gravity load carrying capacity is not compromised in the projected earthquake scenario.
A full scale testing was carried out under quasi-static conditions on a soft-storey building which was representative of existing building stock in low-moderate seismic regions to investigate the force-deformation relationship and drift capacity of soft-storey buildings. Data obtained from the full-scale experimental field studies on the force displacement behaviour of the building has been used as input into the nonlinear time history analyses to study the seismic response behavioral trends of soft-storey buildings.
A new simple methodology for estimating the peak displacement demand of inelastic nonlinear systems, which is based on the elastic displacement response spectra, was introduced. The major findings from the parametric studies shows that highest point on the elastic displacement response spectra can provide a conservative prediction of the maximum displacement demand of non-linear inelastic systems.

To check the problem of weak story is required by using the calculation of the ultimate story shear of each level in our seismic design code. But, this calculation is a complicated method in the design procedure. Especially if we check a high building, it needs a lot of time to manual computing. On the other way, the engineering can use the program of ETABS for analysis. The calculation can be replaced by the nonlinear pushover and the result of comparison will be discussed in this paper. The suggested method shows more fast and safe for checking a high building.

The experience of seismic reconnaissance shows that many buildings severely collapsed in the earthquake due to the walls removed and the story height increased on the first story for the purpose of spaciousness and brightness. Besides, the second and upper stories were often used to be private residence with large numbers of partition walls. The above situation caused the areas of columns and walls of the first story to be significantly lower than the upper stories, and the building thus formed a soft story on the ground floor, with the risk of collapse greatly increased. In order to improve the safety of people''s living, the soft story with obviously insufficient vertical members in the building should be retrofitted to improve the lateral strength and stiffness, so that the deficiency of the soft story can be eliminated. According to the concept of the seismic preliminary evaluation method, the seismic capacity of the building is contributed by the vertical members, so the key to the retrofit design lies in the understanding of the lateral force characteristics of the vertical members. The existing methods of preliminary evaluation are mostly based on school buildings. However, considering the different structural characteristics of school buildings and residential buildings, the relationship between the vertical members and the seismic capacity may not be applicable to residential buildings. Therefore, in order to make this study applicable to various types of buildings, a large number of statistics will be carried out based on Taiwan''s RC building database to acquire the dimensions of various types of vertical members. Then the lateral force displacement curve analysis will be used to obtain the average lateral strength per unit area and strength participation coefficient for the vertical members. And the evaluation formula of the story shear strength and stiffness is established. Finally, a simple retrofit design method to eliminate the deficiency of the soft story for the RC buildings is proposed. This study also uses the proposed evaluation formula of the story shear strength to apply the seismic preliminary evaluation to the buildings in the database and the comparison with the existing methods will be carried out.

Abstract:
AbstractThroughout history, sites of high societal values, such as temples, tombs or palaces were mainly constructed through the digging/carving of rocks, built on hills or plateaus, or through the usage of carved/cut displaced rocks. Ancient designers/engineers/workers usually chose construction sites as to facilitate the building or the carving of stones, while, at the same time, serving the purpose of the building/constructions. In Egypt, throughout the ancient Egyptian Civilization, Egyptians have chosen to carve their temples and tombs in the soft limestone, shales and sandstones that are covering most of the modern Egypt, whereas in few temples and tombs, hard igneous and metamorphic rocks were used as ornament material for tombs and statutes. In this paper, we will present an account of the development of landslide risk assessment for various cultural heritage sites around Egypt, for different eras of Egyptian history and different sites. This paper aims at discussing different case studies and success stories of landslides and block movements hazards assessment around or inside Egyptian Cultural Heritage sites.

Abstract:
A soft storey is one that has a discontinuity in the stiffness of the building where one storey is significantly more flexible than the other storey. In order to tackle the problem of parking space, open ground storey is more preferred. The soft storey effect is the main criteria to be considered while constructing a building with open ground storey configuration. These buildings possess a higher tendency for collapse during earthquake due to soft storey effect. The discontinuity in stiffness will result in large bending moment and shear force action in open ground storey building. The study aims to find out the effects of soft storey configuration in the building with different types of steel bracings under seismic loads. The types of steel bracing include concentric bracing, eccentric bracing and cross bracing. The effect of bracings systems used in soft storey building under seismic load are studied using ETABS software. The different parameters like lateral displacement, bending moment, storey drift, storey shear, storey stiffness needs to be analysed and compared. Response spectrum analysis and nonlinear dynamic time history analysis is carried out to understand the behaviour of building under earthquake loads. From the results it was concluded that, the inclusion of cross steel bracing proved to be the most effective structural configuration closely followed by the concentric inverted V steel bracing configuration in order to mitigate the soft storey effect in all zones. The stability of a building can be improved by using these lateral load resisting systems.

Abstract:
In the concrete era of construction activities, there is scarcity of land especially in metro cities. Even though if there is availability of land it may in the sloping ground, hillocks or on land filled areas, in such areas there will be difficulty in the construction and design aspects. To maintain the slope of the strata, different degrees of such buildings step back towards the slanting slope and may likewise also have set back simultaneously. Hence in the present paper, an attempt has been made to study, G+12 storey building assumed to be in flat ground and also on sloping ground with 20 degree inclination. The model considered to be a soft storey with infill walls and two different shear wall arrangements. The building has been modelled in ETABS software with response spectrum method of analysis. The study reveals that model with shear wall improves the performance of the structure in terms of displacement, drift and time period apart from the fact that the structure being constructed in normal ground or sloping ground.

Abstract:
This paper considers a spatial frame bar finite element for modeling reinforced concrete beams and columns. Both concrete and reinforcement are described by the equations of the deformation theory of plasticity and the theory of plastic flow. Degradation of concrete during cracking is modeled by the descending branch of the σ – ε diagram (the deformation theory of plasticity), as well as the compression of the yield surface and its displacement in the space of principal stresses (the plastic flow theory). The longitudinal reinforcement is considered discretely. It is assumed that there is no reinforcement slipping in concrete. The paper provides the results of the studies that reveal the causes of computational instability related to the presence of a descending branch of the σ – ε diagram for concrete, and proposes ways to overcome it. The reliability of the obtained results is confirmed by comparing them with the results of experimental studies performed by other researchers, as well as with the results of numerical solutions obtained by the particle method. This paper also provides an example of the nonlinear analysis of the fragment of a multi-storey building from the SCAD Soft collection of problems (www.scadsoft.com).
