Abstract
The objective of this research work is to study the shear wall converted to steel braced frame under seismic loads. The behavior of shear walls and braced frames was analyzed using nonlinear static analysis by nonlinear finite element analysis. A parametric study was performed to assess the effect of building height, location of the system, amount of reinforcement, and the fundamental time of the structure on the structural elements capacity.
Shear walls converted to braced frame in top stories were studied by nonlinear static analysis, which uses displacement based design method which depends on element nonlinear behavior to calculate the effective stress and strain which effect on total displacement of the building. The results are presented and show that shear walls can be replaced with braced frame until reaching the buckling load for the steel member. A comparison is created for story drift values with various structural codes.
