COMPARISON OF LATERAL FORCE RESISTING SYSTEMS WITH & WITHOUT RETROFITTED PROVISIONS

Abstract

Comparison of different Lateral Force Resisting System with or without braces was done using different tools which includes both physical and software testing of the model. Braces were provided at different orientation in a frame. Empirical results were obtained using Shake Table. Software results were obtained using Etabs and Mastan2. Etabs was used for linear elastic modelling and Mastan2 was used for non-linear elastic modelling. Both empirical and software results were compared and performance of the structure using a brace was checked. It was concluded that using a brace in a structure improves its performance a lot and the structure was less prone to damage by earthquake loading. Furthermore, it was checked that which type of brace perform best in case of an earthquake.
