Abstract

An emergency seismic retrofit technique is indispensable for the rehabilitation of damaged RC buildings immediately after earthquake attack. There-fore, it is important to develop quick and convenient emergency retrofit technique to recover the seismic performance of the structures damaged by earthquakes. It is well known fact that the strength and ductility of RC columns can be extremely enhanced by transverse confinement which also acts as shear reinforcement. Considering this fact an emergency retrofit technique utilizing pre-tensioned high strength steel bars (PC bars) and steel plates is proposed in this paper. The effectiveness of the proposed retrofit technique is experimentally investigated and analytically evaluated simultaneously.
