Effects of beam members on performance of buildings under seismic forces

Abstract

The main aim of the paper is to present an analysis to study on non-linear seismic analysis of reinforced concrete (RC) framed buildings as per the provisions of Indian code IS1893-2016 to evaluate the response of the building configurations depending upon the section sizes of the horizontal members; beams and as per variation in its cross-sectional area. The response of buildings has been noted in terms of quantities as the time period of buildings.Indian seismic code IS 1893 has been employed for the design provisions of the seismic analysis and the structures have been evaluated for seismic zone II. The design software STAAD.Pro has been used for the dynamic analysis.The response of the structure under lateral force system, induced due to seismic activities is must be analysed to understand the behaviour of structure under dynamic forces. The paper evaluates the most common but important response factors of the structure which are most important in the design of building. The paper also shows the detailed results of the time period of buildings for various building configuration. The evaluated results have been tabulated and analysed with the help of a comparative study of the obtained data. The work is useful for better understanding of the performance of the reinforced concrete buildings as per the different sizes and sections and stiffness of the beam elements.
