Abstract:

For practicing engineers, knowledge of the characteristics of supplemental damping in buildings is essential to understand the resultant effects of added damping. Characterizing the overall system parameters representing the amount and the plan-wise distribution of the supplemental damping in a single-story asymmetrical building is straightforward. However, this becomes a difficult task for multistory asymmetrical buildings. For this reason, this paper first develops the effective one-story building (EOSB), which retains the characteristics of the two dominant vibration modes of the original nonproportionally damped multistory asymmetrical building. By using the EOSB, it becomes convenient to characterize the supplemental damping in the original multistory asymmetrical building. The effectiveness of this approach is verified by using three numerical examples, which include one one-story, three eight-story, and one 20-story asymmetrical buildings. Next, the relationships between the roof displacements of the original building and those of the EOSB are established. This enables the application of the response spectra constructed from the EOSBs to estimate the peak roof displacements of the original multistory asymmetrical building.

Full text

Abstract:

To evaluate the seismic torsional effect on multistory buildings, the concept of eccentricity is extended from single-story buildings to multistory buildings by defining the locations of the centers of rigidity at each floor. A practical procedure to locate the centers of rigidity and hence floor eccentricity is introduced. This procedure depends on the use of plane frame computer programs only and is suitable for use in design offices. The seismic torsional provisions in the National Building Code of Canada 1985 (NBCC 1985) explicitly emphasize that the code provisions apply to buildings where the centres of rigidity lie on a vertical axis only. By means of examples, it verifies the claim of NBCC 1985. Also, it shows that, for buildings with centers of rigidity scattered from a vertical axis, the code procedure may or may not apply. Therefore, one should interpret the condition of centers of rigidity located along a vertical axis to be a sufficient, but not a necessary, condition for the NBCC 85 code provisions to be applicable. Until the necessary conditions are known, dynamic analysis remains the most reliable method to assign the torsional effects to various portions of the building. Key words: building code, center of rigidity, dynamic analysis, eccentricity, irregular, multistory, seismic, torsion.

Abstract:

Multistory models are studied to assess design recommendations for torsionally unbalanced multistory buildings. Structural systems are assumed as shear beams with nonlinear lateral-resisting elements oriented along two orthogonal directions and subjected to a bidirectional earthquake ground motion. Five-story rigid-diaphragm models with mass or stiffness eccentricity are considered in the study. Accidental eccentricity is not included in the modeling and, therefore, its related recommendations are not assessed. Design recommendations studied here are based on the simple static procedure and include two values and an expression for the amplification factor α to compute story eccentricities, three values of the torsion-shear reduction factor δ, an additional lateral force Ft to be applied at the building top level, and a minimal story eccentricity for the building. Design recommendations to control ductility demands of torsionally unbalanced multistory buildings are given.

Abstract:

As the essential vertical transportation in multistory or high-rise building, stairs is very important. When2008, 5.12Wen-Chuan earthquake occurred, many staircases were seriously damaged especially in the multistory framework structures which were built in recent years. It seems probable that some common fault happened in the design work. In the multistory framework the stairs member may contribute stiffness as a "K"-shaped brace which effecting the deformation of the frame notably, triggering tension or compression to the stairs plate, however, the "K"-shaped brace effecting were neglected in the design courses. This paper analysis the seismic damage of staircase and stairs, puts forward in multistory framework, the design of stairs can choose "rigid" or "flexible" solvent. The suggested methods can be use either to repair the existing stair structure or to design stairs for new frame building in order to improve the structural function of stairs and the overall building.

Abstract:

Abstract The rising interest in wooden multistory buildings (WMSB) has led to multiple studies investigating how construction professionals perceive different structural frame materials. These investigations, however, exclude viewpoints from public employees (i.e., civil servants), who are central to driving the implementation of WMSB. This study is part of a broader inquiry to examine perceptions from Finnish civil servants who are responsible for municipal land-use planning and development. To this end, a questionnaire applying the theory of planned behavior was designed. Civil servants were asked to evaluate how strongly they believe WMSB possess 16 attributes in comparison to concrete multistory buildings (CMSB). The attributes constitute statements concerning various economic, social, and environmental impacts of multistory buildings, as well as technical properties. Responses (N = 273) indicate that WMSB are believed to possess positive environmental attributes and to support economic development. In contrast, CMSB are regarded to have lower construction and maintenance cost and to be less susceptible to fire. Furthermore, exogenous factors, like demographics, previous experience, and social environments, were significantly correlated to respondents' beliefs. Especially prominent was the relationship between profession and beliefs about technical and environmental attributes. Future research should focus on determining whether the set of attributes assessed in this study are relevant to the implementation of multistory building projects within Finnish municipalities.

Abstract:

An investigation has been carried out to study the effect of the wind parameters on the response of multistory buildings subjected to wind induced forces. This study is concerned with the wind response of the buildings located at six building sites in Sohar, Thumrait and Saiq regions of Oman. A typical plan of multistory-framed building has been chosen for the present investigation. The Wind and the other related data appropriate to these regions have been used in the analysis. It turns out from the present study that the response of the building located at a Site in a country terrain of a region has higher values than the response obtained for the same building if constructed in a town terrain of the same region With other parameter combinations remaining invariant. It is recommended that a database for the wind parameters, based on the available wind and other related data for different regions of Oman, should be developed for the design of buildings subjected to wind induced farces.

Full text

Abstract:

This study presents a novel method for accurately predicting the dynamic behavior of multistory frame buildings under earthquake ground motion. The proposed method allows approximately estimating the inter-story drift ratio, a crucial parameter strongly associated with building damage, its distribution along the building height, and its maximum value location. An equivalent continuous beam model with a rotation at the base, consisting of a combination of a shear beam and a flexural beam, is proposed to achieve this. This model derives closed-form solutions for the building’s dynamic characteristics. The lateral deformations along the height of frame buildings subjected to a given earthquake load, particularly the inter-story drift ratio profiles, and the maximum inter-story drift ratio parameter, are investigated. The proposed continuous model requires two dimensionless parameters: the lateral stiffness ratio (α) and the rotation at the base (θ), representing the drift ratio of the first story. For the expression of the lateral stiffness ratio (α) coefficient, a simple equation is also proposed using the beam-to-column stiffness ratio (ρ, or Blume coefficient) associated with the framed (discrete) system. Various building models are employed to validate the proposed method, demonstrating its applicability to both high-rise and low-rise building configurations. With the results obtained, it is shown that the proposed continuous model can be used not only for high-rise or multistory building models but also for low-rise building models.

Full text

Abstract:

It has been found that any one vibration “mode” of an inelastic multistory two-way asymmetrical building structure can be represented by a three-degree-of-freedom (3DOF) modal system representing two modal translations and one modal rotation. This study introduces the inelastic response spectra constructed from the inelastic 3DOF modal systems, which is specifically useful for multistory two-way asymmetric-plan buildings subjected to bidirectional ground excitations. These spectra for asymmetrical structures (SAS) provide the three-component inelastic peak modal responses of multistory two-way asymmetric-plan buildings subjected to bidirectional ground excitations. In order to construct the SAS, the independent elastic parameters of the 3DOF modal systems were identified and the inelastic 3DOF modal parameters versus the strength ratio relationships were established. The parametric study of the 3DOF modal parameters showed the ranges and the variation trends of these parameters. Two example buildings are analyzed to verify the effectiveness of the above-mentioned investigations.

Abstract:

In present scenario buildings with Stub column is a typical feature in the modern multistory construction in urban India. Such features are highly undesirable in building built in seismically active areas. This study highlights the importance of explicitly recognizing the presence of the Stub column in the analysis of building. Alternate measures, involving stiffness balance of the first story and the story above, are proposed to reduce the irregularity introduced by the Stub columns. FEM codes are developed for 2D multi story frames with and without Stub column to study the responses of the structure under different earthquake excitation having different frequency content keeping the PGA and time duration factor constant. The time history of floor displacement, inter story drift, base shear, overturning moment are computed for both the frames with and without Stub column.

Abstract:

In multi-storey buildings that are asymmetrical in plan, an eccentricity occurs between the center of mass and the center of stiffness. Under the action of wind and seismic horizontal loads, torsion appears in the bearing system of the building. Torsion can also occur in nominally symmetrical buildings caused by uneven deformations of structural components. There are numerous analytical and experimental studies of the effect of torsion on bearing structures. It is required to assess the achievement of the ultimate states of reinforced concrete structures and shear bonds that create a spatial system. This paper uses computer simulation to study the stress-strain state of the welded bond under the action of shear and torque. Two joint models are considered, which are subject to only shear and shear with torsion. The results show the process of destruction of the joint, deformation of the shear walls to be joined, and a decrease in the rigidity of the connection. The study is useful for understanding the mechanisms of twisting effects during translational and rotational vibrations of a building.

Abstract:

Low-rise office buildings constitute a large portion of the building inventory that is governed by criteria published by the US government. In recent efforts to save costs, building owners and others in this construction sector have explored the use tilt-up construction for these facilities, which eliminates the perimeter steel framing and integrates the concrete façade into the load bearing structure. According to the criteria, many of these buildings meet the height and occupancy thresholds for which progressive collapse resistant design is required. Two major US government agencies, DoD and GSA, provide methodologies for progressive collapse analysis of common structural systems. However these guidelines include limited guidance for the design of tilt-up construction. This paper outlines a methodology for progressive collapse resistant design of tilt-up structures and discusses the increases in reinforcement needed for a prototype building.

Abstract:

This paper describes a method for localizing wireless mobile clients in a multistory building using a public wireless Local Area Network (LAN) system. Physical location data on personal devices and mobile robots is important to information services and robot applications. Wireless mobile clients are localized in a multistory building using public wireless LAN access points placed, three-dimensionally in the building. Information on the floor number and client location is acquired probabilistically, with estimation providing a probabilistic model for localization based on sparse Bayesian learning. Results of experiments confirm the feasibility of our proposal.

Abstract:

bstract: As per latest statistics, India comes under more denser oriented in terms of living in populated countries and by analysis, it is directly proportional to the land shortage problem. To overcome this problem, now engineers make a structure taller in height and having more land coverage area with aesthetic view is the only option available since it provides more suitability in less space. Also, architectural point of buildings are very famous and client prefer this type of structure. The main problem is to stable the architectural building when there will be instability due to attractive building looks. In this study, various papers associated to this topic are intensively studied and have gone through deep analysis in which an enormous work is done in this field earlier. To make these buildings more stable, literature review has conducted that came to know the conclusive outcome which forms the research objectives of our further technical study.

Abstract:

Since a long time ago, Padang City has been recognized as one in most-earthquake and tsunami prone city in the world. The successive significant earthquakes that have struck western coast of Sumatra Island from 2004 to 2010 seems to warn the city about its prone condition. The last major Padang-Pariaman earthquake on September 30, 2009, for instance, has caused hundreds of death and lousy damage to thousands of houses and buildings in city. Recently, several new multistory reinforced concrete (RC) buildings have been established in this area. Its include such buildings as government office, mosques, hotels, school and university. The city government plans to use these buildings as vertical evacuation facilities if an earthquake followed by a tsunami hit the city in the near-future. As a consequence, of course, these infrastructures should be well designed and constructed to resist the future earthquakes motion. This paper discusses an evaluation of the seismic performance of an existing multistory RC building in Padang city. The building was a ten-story of hotel RC building located near the coastline of Padang city. A series Pushover and Time History Analyses were conducted to examine the seismic performance of the target R/C building. It uses STructural Earthquake Response Analysis (STERA-3D), a computer software based on the nonlinear finite element method. The Pushover analysis was conducted for maximum drift ratio 1/200 in X and Y directions, respectively. The input ground motion in a maximum acceleration of about 400 gals and 600 gals for 60 seconds’ excitation were used for the Time History Analysis. These input ground motions were generated from the recorded ground motion of 2009 Padang-Pariaman earthquake. The result of the analyses suggest that the current target multistory RC building has outstanding seismic performance. The result is based on the level of damage of the structural components, base shear, inter-story drift, lateral displacement, dynamic responses and the seismic capacity spectrum of the analytical model.

High-rise buildings may experience high levels of vibrations under the actions of wind which cause building motions, adversely affecting serviceability and occupant comfort. The paper analyzed the vortex shedding responses of a multistory building with moment resisting frame. It presents a numerical model based on computational wind engineering technique to simulate the wind action over a typical high-rise building using wind speed data of Lagos state Nigeria. The vortex shedding frequency of the vortices and the natural frequency of vibration of the entire high-rise building structural system were calculated by computing fast Fourier transform algorithm (FFT) of the force coefficient and finite element analysis (FEA) of the structural system respectively. From the result obtained, the vortex shedding frequency of the wind vortices was lower than the fundamental frequency of vibration of the typical high-rise building. Hence, vortex shedding was not responsible for the failure of high-rise buildings in the locality being considered due to the reasons stated in the author’s conclusion.

Full text

Abstract:

The use of modal analysis appears necessary in order to reduce both displacement demand under weak seismic events and ductility demand under strong earthquakes. Static analysis can be effective only if used with proper values of additional eccentricities. To overcome the inaccuracy of the code formulations, the authors propose a simple procedure that gives the exact values of these eccentricities and discuss the influence of the main parameters that govern the structural behavior. They also point out the difficulty in evaluating some parameters (stiffness radius of gyration, structural eccentricity) in the case of multistory buildings and discuss the validity of simplified formulations proposed to overcome this problem. The effectiveness of static analysis, applied to three-dimensional multistory structures with properly evaluated corrective eccentricities, is analyzed with reference both to regularly asymmetric multistory schemes and to an actual irregularly asymmetric structure (the main building of the Faculty of Engineering at the University of Catania, Italy).

Abstract:

The buildings of business centers make up a significant part of the development of modern cities. Having different sizes, functional content and architectural and artistic solutions, these complexes are often spatial dominants. The compositional accent formed by them indicates the place of concentration for social activity associated not only with business activity but also often with an entertainment pastime program. The formation of a business center as a specific type of building has a long history from open or semiclosed spaces in ancient times, in which trade operations were carried out, to modern multifunctional, multistory buildings. These buildings are located singly or form complexes occupying one or more blocks. Business centers in Kazakhstan developed in a peculiar way, having a break in their development. The analysis carried out made it possible to identify a number of characteristic features of this development. The post-COVID-19 period has formed a new stage in the evolution of business centers. Demand for this type of building has partially declined. Existing buildings began to partially or completely reorient themselves to other activities. At this stage, the most promising option for multistory complexes is their transformation into hotels or residential buildings.

Abstract:

The cold formed steel section are increasingly used as a structural elements in low rise buildings in recent times, due to the advantages like economic production, easy transportation, low labor cost and high strength to weight ratio. In the current work a G+3 storied building frame is studied for seismic and wind load using Staad-pro software. Light gauge section is taken for beam and slab elements. The seismic analysis is carried out by Equivalent static method. After analysis the results such as story displacement, story drift, Base shear and time period are compared for different models. The building frame is also analyzed for wind load. In the current work cross bracing using Light gauge element used as a retrofitting technique. The retrofitted building frame is analyzed for wind and seismic loads and results obtained for time period, storey displacement, storey drift and base shear values are compared with the corresponding values of base frame. The results of retrofitted frame showed shortening in time period, storey displacement and story drift values in X&Z directions indicating the increased ductility, Stiffness and strength of structure. Hence the proposed retrofitting technique could be believed to achieve success results in increased strength and ductility values required by wind and seismic loading.

Abstract:

In the last three decades, preference was given to the construction of monolithic buildings, but the construction of multistory frame buildings from prefabricated concrete is very relevant at the present stage. Therefore, there is a need to revise the normative base for the design of prefabricated housing construction, including the revision of standards for certain types of prefabricated reinforced concrete structures. Such work is currently being carried out taking into account the use of modern building materials, new technologies for the production of prefabricated structures and the erection of prefabricated buildings, as well as taking into account the widespread use of computer design methods in design practice. The Code of Rules for the design of multistory frame buildings in prefabricated concrete SP 356.1325800 was developed as an extension of the Code of Rules for the design of reinforced concrete structures SP 63.13330. The article reviews the normative and technical literature on the computer simulation of load-bearing elements and junction units of the calculation scheme of multistory frame buildings. The means of the LIRA software package for computer simulation are considered and a quantitative assessment of the stiffness of the connection in the hinged joint of the crossbar with the column, as well as a flat model for assessing the stress distribution in the cantilever of this joint, is proposed.

Abstract:

Overhead water tank commonly used in buildings for various requirements. Overhead water tank is not only for water supply which also control the displacement of building during the earthquake force acting on structure. RCC over head water tank which gives the certain mass to the building this mass reduce the lateral movement of the building during seismic force on structure. In multi story structure, water tank also will lead the important factor for reducing the seismic response of the building. Using this technique overhead water tank placed on asymmetrical multi story building at different places. In thatone particular location reduce the seismic response more that place is choose for placing water tank. The advantage of this method isoverhead water tank is used for water supply as well as controlling of seismic response. Response spectrum analysis are used for analysis the structure in ETABS software. This software is used to checking the particular location for fixing the overhead water tank.IS standards are used for this analysis. In this experiment purpose the G+10 building is analysed in this study. This method is very economical it save the extra money for strengthening the building.

Abstract:

Abstract Wood products are seen globally as an important solution to substitute nonrenewable materials in the construction sector to enhance the life cycle sustainability of buildings. Globally, the most prominent opportunities for sustainability change in housing production lie in multistory residential buildings, which are built mainly of concrete, steel, and bricks. The possibilities of achieving multiple benefits from the use of wood in multistory residential buildings have gained interest among scholars, especially in the 2000s. However, the research has been dominated by views of production (especially construction processes), while scientific knowledge of consumption (especially the occupational phase of buildings) remains very limited. Information about how consumers with differing views of sustainable consumption evaluate the quality of wooden building materials particularly is scarce. This study aimed to investigate consumer perceptions of wooden building product quality and examine how the perceptions connect with consumers' consciousness for sustainable consumption (CSC). The research data were gathered in 2018 by a postal survey sent to 1,000 people living in Finland (response rate 25.6%) and analyzed with exploratory factor analysis and the Mann-Whitney U test. According to the results, respondents' views of wooden building product quality indicators can be grouped into three factors: technical advantages, environmental sustainability of materials, and social benefits at home. The strength of CSC was found to be linked with respondents' views of wooden building product quality. The results of consumers' CSC views help actors involved in the wood and construction industries better meet consumer expectations both for different aspects of sustainability and for lifestyles.

Abstract:

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.

Abstract:

When evaluating seismically induced second-order effects in buildings, engineers and researchers are most familiar with these concerns in the context of multistory buildings with rigid diaphragms. However, similar concerns are valid for short single-story concrete or masonry-walled buildings with larger flexible diaphragms, which is a significant portion of the building stock in the United States. These rigid wall-flexible diaphragm (RWFD) buildings may have significant diaphragm drifts causing induced second-order effects. The stability coefficient currently found in ASCE 7 has traditionally been used by practitioners to evaluate the relative risk of P-delta instability in multistory buildings, but this indicator can be adapted for use in RWFD buildings. Using numerical studies following the Federal Emergency Management Agency (FEMA) P-695 collapse assessment methodology to evaluate the risk of collapse for a set of RWFD archetype buildings, a modified stability coefficient for RWFD buildings is found to capture the trend toward P-delta collapse and can act as a reasonable indicator without the need for heavy computational efforts.

Abstract:

Contribution in the building sector to the global warming can be tackled by diminishing greenhouse gas (GHG) emissions (mainly CO2) not only from operational energy but also from the embodied energy (EE) of construction materials. Harvested Wood Products (HWP) such as Cross Laminated Timber (CLT), Glued Laminated (Glulam) timber, among others, make multistorey wooden buildings possible. These wooden buildings could help to reduce EE and CO2 emissions significantly. A material flow analysis (MFA) using an I-O (Input-Output) table was used to compare three scenarios for an 8-story apartment building in Indonesia (total floor area: 9140 m2): First, the building had a reinforced concrete structure. Second, the building had a “hybrid” structure with reinforced concrete cores and first-floor elements, consisting of CLT floor panels, and Glulam columns and beams. Third, the building used only CLT panels besides reinforced concrete cores. The results showed that the last scenario achieved the largest CO2 emissions and embodied energy reductions (58 t-CO2 and 905 GJ), compared with the first scenario (81 t-CO2 and 1110 GJ). Furthermore, we compare two methods to apply displacement factors (DF) to assess the CO2 emissions savings for each CO2 ton in wood products substituted in place of non-wooden products between the three building scenarios.

Abstract:

Abstract Two models have been developed to predict airflow and dispersion in urban environments. The first model, the Realistic Urban Spread and Transport of Intrusive Contaminants (RUSTIC) model, is a fast-running urban airflow code that rapidly converges to a numerical solution of a modified set of the compressible Navier–Stokes equations. RUSTIC uses the k–ω turbulence model with a buoyancy production term to handle atmospheric stability effects. The second model, “MESO,” is a Lagrangian particle transport and dispersion code that predicts concentrations of a released chemical or biological agent in urban or rural areas. As a preliminary validation of the models, concentrations simulated by MESO are compared with experimental data from wind-tunnel testing of dispersion around both a multistory rectangular building and a single-story L-shaped building. For the rectangular building, trace gas is forced out at the base of the downwind side, whereas for the L-shaped building, trace gas is forced out of a side door in the inner corner of the “L.” The MESO–RUSTIC combination is set up with the initial conditions of the wind-tunnel experiment, and the steady-state concentrations simulated by the models are compared with the wind-tunnel data. For the multistory building, a dense set of detector locations was available downwind at ground level. For the L-shaped building, concentration data were available at three heights in a lateral plane at a distance of one building height downwind of the lee side. A favorable comparison between model simulations and test data is shown for both buildings.

Abstract:

During the September 19, 1985 earthquake about 60 post-1957 multistory steel buildings in Mexico City were subjected to a severe test. In most cases, the damage in the post-1957 structures was minor to moderate. The notable exception is the Pino Suarez complex in which one 21-story building collapsed onto a 14-story building, and two other 21-story buildings were severely damaged. The behavior of these buildings as well as two other case studies are analyzed. Conclusions are drawn on the ductility demands imposed on steel buildings in Mexico City, utilizing simplified structural models and considering the actual strength of buildings that may be much higher than the code design strength.
