Evaluating the Seismic Performance of Modern Concentrically Braces with the Finite Element Method abstract
The use of modern steel braces is one of the ways to increase the lateral stiffness of the structure. Comparing and determining the advantages of braces helps structural designers to make a good design. Therefore, in the present paper, the 2-story steel structure (2D) is designed with finite element method (FEM) and ABAQUS software. Steel frames are seismically improved with Rhombus, V and Inverted V braces. Structures are seismically evaluated during modal analysis in the frequency domain. The results show that the Rhombus brace reduces von mises stress (0.68%), displacement (to a small amount) and eigenfrequency (11.85%) in the steel frame. Rhombus brace has the best seismic performance compared to V and Inverted V braces during modal analysis in the frequency domain.
