Abstract
In multistory building there a lot of parameters of concern which need to be considered for the effect of
earthquake and wind load. There are many ways by which the performance of a building during the seismic activity can
be improved. Bracing is one of the best method for lateral load resisting system as it is economical and easy to apply. This
paper compares the response of building with different types of bracing systems such as X, V, inverted V , Knee bracing
and single diagonal bracing. It also compares the seismic behavior of structure under the concentrically and eccentrically
braced frames using ETABs and different methods of analysis like Response spectrum, pushover and Time History
analysis.
