The seismic performance of multi-storey buildings is controlled by their lateral load resisting system. In recent few years, several new structural techniques have been developed to improve the performance of reinforced concrete (RC) multi-storey buildings subjected to lateral stiffness and the excitations. The use of flag wall system (i.e. the RC walls in selected floors, not reaching the foundation) can be an efficient way to achieve this goal. The flag wall at the selected place and location checks the linear static and linear dynamic analysis and will finds the local response like Lateral displacement, Base shear, Storey stiffness, Storey drift by using ETABs software with different patterns. This study based on earthquake zone III and soil type is medium soil and building construction type is RCC building. This study evaluates the seismic performance of such flag wall structural systems used as an alternative to evaluate optimum location of flag wall.

Tall buildings structure has been a considerable increase in both residential and commercial as well as modern Trend structures. There are two systems comprise the most attractive and commonly used now a days are flat slab and shear wall system. Flat slab is most widely used system in reinforced concrete construction in offices, industrial buildings etc. It supports floor slab without beams. When it comes to seismic performance or lateral force flat slab tall buildings without shear wall is relatively less when compared to with shearwall.in this study I have done two models of flats slab tall buildings one with shear wall and another one without shear wall by using ETABS software. The comparison of analysis results will take place in order to see how both a buildings are performing under lateral and seismic loads and finding a seismic parameters like time period, base shear, lateral displacement, and storey displacement are checked out.

This study investigates the direct displacement based design (DDBD) and convectional force based design (FBD) approach for 8 storey RC frame building in DDBD methodology the displacement profile is calculated and the given MDOF is converted to equivalent single degree of freedom system. After calculating the effective period, secant stiffness, and viscous damping of the equivalent structure, the base shear is obtained, based on which the design and detailing process can be carried out. The designed frames as per DDBD and FBD approach are then analyzed using nonlinear pushover analysis to obtain the capacity curves and response reduction factor. Results of the analysis and comparison of ‘R’ factor indicate the efficiency of the DDBD approach for RC frame buildings

The World

The two stories building construction or which is commonly called the two stories building these days is very popular in Indonesia. The type of multistories building technology that develop in the world of construction is very diverse, this development is can not be separated from the anticipation of the various of loading conditions. Based on that facts, the research of the use of lintel beams in 2 stories infilled frame buildings is conducted. The analysis can be done by using SAP2000 software. The structure model analyzed by comparing the structure responses between the building that use the lintel beams system and the other one is the building that don’t use that system, where as the idealized loading is same. The result of the analysis obtained by using the lintel beams system the value of maximum x and y axis base shear respectively are 344,088 KN and 363,001 KN, the maximum column moment is occurred in column 84 with the value is 99,58 kNm, and the maximum x axis lateral drift is occurred in joint 128 with the value is 0.000401 m, while the y axis is occurred in joint 105, 128 with the value is 0,000533 m. The analysis result that obtained for the building that don’t use the lintel beam system, the x and y axis maximum base shear value respectively is 336,425 KN and 354,539 KN, the maximum column moment occurs in column 84 is 98,98 kNm, and the x axis maximum drift lateral occurs in joint 128 with value is 0,000406, while the y axis maximum lateral drift occurs in joint 105, 128 with value is 0,000532. So we obtained the percentage comparison on base shear value between 2 stories infilled frame building that use lintel beams system and the building that doesn’t use the lintel beams system for x axis is 1,45% and y axis is 1,13% , and for the percentage comparison on maximum column moment value is 0,30% , while the percentage comparison on drift lateral value for x axis is 0,62% and y axis is 0,09%

Buildings are designed in different methods for resisting the lateral loads, in which strong column weak beam concept is one of the methods of designing, this method is used to avoiding the global failure of the structure In this work 3bay 5 story RC frame building is consider for the analysis, the structures are design strong column weak beam with the help of static non-linear pushover analysis of RC frame building with increasing the percentage of column sizes 20%, 40%, 60%, 80% and 100%. By varying with percentage of columns resistances of structure is increased. The parameters base shear, story displacement, and hinge formations in the structure is obtained from this analysis. The base shear and displacement are increased by increasing the column sizes, these parameters are discussed the results in detail. Comparing the all six model results the base shear in increased by 266.64% when the column size is increased by 100%. From this analysis we can reduce the failure in the structure during the earthquake. Formation of plastic hinges in column changes to beam by increasing the column size, so increase the capacity of structure. The building is analyzed by using SAP2000.

AbstractMany reinforced concrete (RC) frame buildings in Nepal were significantly damaged by the 7.8 magnitude (Mw) earthquake in Nepal on April 25, 2015. To contribute to mitigate future earthquake disasters, the current study focuses on two specific characteristics of residential RC frame buildings in the capital city of Nepal, Kathmandu: the application of brick masonry infill to exterior and partition walls, and the conventional vertical extension of building stories different from the design. Although these factors are likely to significantly affect the seismic performance, their effects are frequently neglected in practical design and construction management in developing countries. Hence, the main objective of this research is to investigate and clarify the seismic performance of RC frame buildings considering the above factors through experimental and numerical investigations. The present paper (1) briefly introduces the characteristics of a typical residential RC frame building in Kathmandu, (2) illustrates the numerical modeling parametrically considering three different contributions of brick masonry infill walls and (3) investigates the seismic performance of the RC frame building considering the effects of the infill wall modeling and the vertical extension through numerical analyses. Consequently, it was found that the consideration of the in-plane stiffness and strength of the infill walls resulted in both positive and negative contributions to the seismic performance of low-rise (up to three stories) and medium-rise (more than three stories) buildings respectively, quantitatively clarifying significant effects of the presence of infill and the vertical extension. These findings contribute to provide realistic solutions to upgrade the seismic performance by utilizing or removing the brick masonry infill walls or by managing the building stories to mitigate future earthquake disasters on typical RC frame buildings not only in Nepal but also in other countries with similar backgrounds.
