Abstract

One of the new methods of anchoring steel structures is the use of large-scale buckling-restrained braces (BRBs) on the lateral system of this type of structure. This study investigates the behavior of BRBs and compares them with buckling braces. In this study, a two-dimensional frame with four stories and four spans was taken and analyzed in eight different ways, and each in the form of buckling and buckling-restrained braces. The results show that making the braces buckling-restrained has a positive effect on increasing ductility and energy dissipation.
