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.
