Comparative study on seismic analysis of reinforced concrete building in different earthquake zones of Bangladesh

Abstract

Due to emergence of earthquake prone areas, earthquake analysis is becoming one of the key aspects in the design of any structure. This study was undertaken with a view to determine the extent of possible changes in the seismic behavior of RC Building Models for different seismic zones. The study highlights the effect of seismic zone factor in six different zones, which is considered in the seismic performance evaluation of buildings. Adding to that, performance of RC building due to wind variation in similar seismic zones has been also evaluated. The present study is aimed to find out the spatial changes of three major parameters– Story Drift, Story Shear and Story Displacement in different seismic areas as well as to figure out the consequences of same building when subjected to wind load of different speed in similar seismic zones. From our findings, the seismic effects is higher whenever seismic coefficients gets higher and eventually the seismic intensification varies with respect to it's coefficients. And for wind load, the wind speed governs in similar seismic zones.
