Abstract :

Buckling restrained brace (BRB) is an energy dissipation structural system. This research has been numerically investigated the energy capacities of BRB by finite element (FE) modeling using ABAQUS software. The research concluded that core yield stress and thickness are the main contributing factors towards affecting the load-carrying and energy dissipating capacities of the BRB. It is also observed that using an excessively high yield-to-total length ratio increases the chance of global buckling for the BRB system. Conversely, using low yield-to-total length ratio triggers excessive stretch in the steel core, especially when higher steel grades are used.
