Overview of Seismic Retrofitting Building

Abstract: Earthquakes around the world are single-handedly responsible for the destruction to life and property in large numbers. In order to mitigate such hazards, it is important to incorporate norms that will enhance the seismic performance of structures. This report provides criteria to evaluate the performance of existing buildings with steel and composite structures, either framed or braced. It also presents a comprehensive review of rehabilitation strategies to retrofit structural members and connections and frames The overall aim of the present study is to know and understand the behavior of certain structures under seismic activity and how different parameters affect retrofitted structures. It may be achieved by adopting one of the following strategies- - By reducing the seismic demands on members and the structures as a whole - By increasing the member capacities. Keywords: seismic retrofitting, rehabilitation, repair, seismic.
