Dynamic Analysis of Open Ground Multistorey Building Using Response Spectrum Analysis in STAAD.Pro for Different Seismic Zone

Civil Engineering

In these advanced days the Buildings are made to satisfy our essential perspectives and better Serviceability. Presence of infill walls within the frames refers the behavior of the building under lateral loads. However, it's a common experience, observe to ignore the stiffness of the infill frame for analysis of framed building. The infill strut provides the ability to reduce the lateral load in structures. In this work, the infill strut has been replaced at open first storey building to provide the maximum stiffness to the structure as compared to bare frame or normal OGS frame structure. The present work is done in STAAD. Pro software, which is a good agreement for seismic structure analysis. In this research work the analysis of seismic effect on residential building of G+4, G+7 and G+10 stories supported on a raft foundation for three seismic zones i.e. III, IV and V in India and obtained the storey shear, base shear, maximum deflection and base moment by using software. The dynamic analysis of structure is carried out using Response Spectrum Analysis as per the procedure read down in IS 1893:2002. The various results are obtained during analysis and these results are compared to bare frame and infill OGS frame and improve the design for future application.
