Abstract

The past earthquake experiences in India clearly demonstrated that the typical structural design and construction methods lacks the basic seismic resistance criteria. The implementation of ductile design and detailing practices in ordinary building is one of the major area need to be focused. The overall ductility in reinforced concrete structure is a tough issue. But in some strategic locations of the building structure certain design factor and reinforcement detailing can be adopted to minimise the seismic damage and life threatening collapse. The techniques are simple, inexpensive and elaborately discussed in the bureau of Indian standard code of practice (IS13920: 1993). The structures need to be designed to have sufficient strength and ductility for overall safety against earthquake forces. Both the strength and the ductility are combined together to improve its seismic safety. This study discussed the ductile behaviours of the reinforced concrete structures according to Indian code. It also evaluates the earthquake resistance performance of structure based on design and detailing parameters. The curvature ductility in beams with reference to the percentage of reinforcement and design material stress is considered. The behaviour of beam-column joints and the confinement in concrete columns are also addressed.
