Abstract: The present work attempt to study the behaviour of building designed for gravity loads only under the effect of lateral seismic load. The buildings found deficient are then retrofitted by providing shear link with the help of chevron braces to improve its performance. It also provides the literature study of various types of energy absorbing devices that can be implemented in improving the behaviour of deficient RC frame buildings. Past earthquakes have shown a great deal of damages to the deficient RC frame buildings design without any considerations to lateral seismic load. Chevron braces with shear link can be implemented as an effective retrofit measure. In the present study the behaviour of buildings designed for gravity load only have been worked out by performing nonlinear static pushover analysis. It also provides a step by step procedure to retrofit deficient RC frame building by implementing chevron braces with shear link. The behaviour of retrofitted buildings is then worked out by performing nonlinear static pushover analysis and series of nonlinear time history analysis. Parametric study has also been done to study the behaviour of shear link, forces in brace and column after implementing retrofitting scheme. Based on analysis done finally conclusions and useful recommendations are made at the end.
