Structural Audit of Old Building And It's Strengthening : Review

Abstract

We are building the structures rapidly in the area where there is requirement of the structures. Every structure has its own service life. Every structure is designed by assuming its life of existence. Some of the structures gets more life than expected and some gets fail in achieving its life. Any technology or material has its limitation to withstand. Many of the structures of R.C.C. are located in Seismic prone area. The structures gets damaged due to earthquake and the structures which becomes old should be checked that whether it has the strength of existence or not. The structures should be audited timely for the safety of the human life as well as for the nearby structures. The structures can be checked by various methods of Non-Destructive Test (Rebound Hammer Test, Ultrasonic Pulse Velocity Method, Pulse Echo Method, Probe Penetration Test, Destructive Test. Rebound Hammer Test of Non-Destructive Test is used in this paper to check the strength of an institutional building. When examining the structure, this paper aims to expand the life of structure. Different techniques of Retrofitting is given to the structural member which is unsafe. By applying the retrofitting, the structure can be made safe.
