Retrofit of Existing building in Islamabad using
Nonlinear Static Analysis

Abstract: One of the remedies for
earthquake hazards reduction is seismic retrofitting.
But without using intervention technique which is based
on seismic evaluation of the building structure, it may
not be possible to improve the seismic performance of
the building structures by the use of retrofitting. In
this paper the simulation of a building is performed by
using nonlinear static “push over” analysis. The said
building is 4storey RC building. In this work the real
site based demand spectra is compared with the demand
spectra of “ATC 40 procedure”. The simulation performed
is then compared for the sake of evaluation with or
without retrofitted structure. For various safety
margins the plastic hinges are plotted.
