Abstract

Buildings must be able to safely 
withstand any significant ground vibrations that may 
occur during their construction or regular operation 
in order to be considered earthquake resistant. 
Structures that are exposed to severe ground 
movements are best analysed using the time-history 
method. On the other hand, the impact that ground 
movements have on structural reactions is unlike 
any other.This work will focus on the analysis of 
steel-framed buildings, specifically the pushover 
analysis, which is a static nonlinear process that 
estimates seismic structural deformations using a 
simplified nonlinear technique. The capacity curve 
or force displacement relationship of a structure or 
structural part may be found using this incremental 
static analysis. The analysis begins with a pattern of 
horizontal loads being given to the structure in a 
predefined manner. To put it another way, the 
structure is pushed gradually, and the total applied 
shear force and accompanying lateral loads are 
plotted at each increment until the structure reaches 
the collapse state. This approach involves applying 
certain lateral loads to a building model on a 
computer, such as inverted triangle or uniform 
loads. As the lateral load is incrementally raised, 
each structural component is monitored for 
fractures, yielding, plastic hinge creation, and 
eventual collapse. The weak points in the structure's 
seismic performance may be uncovered with 
substantial information using pushover analysis. 
This study uses pushover analysis to examine the 
performance point seismic response of steel-framed 
buildings and the influence of earthquake stresses on 
the frames of multi-story buildings. The current 
investigation involves the design of a building frame. 
as specified in Indian Standards (IS) 456:2000 and 
IS 1893:2002. The primary goal of this research is 
to determine the potential performance of a building 
when constructed in accordance with Indian 
Standards. Only during zone-3 earthquakes is the pushover 
study of a steel-framed building performed using the 
structural analysis program E-tabs.
