Effect of seismic zone and soil type on linear time history behavior of RC framed building

Abstract

In view of structural engineering, the in assessment of seismic vulnerability of structure plays an important role in the analysis and design of structure. A variety of methods are in practice to carry out lateral load analysis on structure due to earthquakes. In this respect, time history analysis is a method to analyze a structure subjected to a specific earthquake ground motion. The seismic response of a structure majorly depends on type of soil and seismicity of location of structure.In this context an attempt is made to study the Linear Time History behavior of a G+5 RC framed building subjected to Bhuj earthquake ground motion considering the effect of soil type and seismic zone factor in accordance with IS-1893-2016 (part-1). A G+5 RC framed residential apartment building is modeled in ETABS 2015 software and analysis is carried out using time history function subjecting to Bhuj earthquake ground motion data for different values of seismic zone factor and soil types. Responses such as base shear storey shear distribution and peak roof displacement are reported for different zone factors and soil type and tabulated the analytical study depicts that, with increase in seismicity of location of the structure, both base shear and peak roof displacement are been increased. Also, with increase in flexibility of soil, both base shear and peak roof displacement are been increased.
