Analysis of the Damage Quantity of Buckling Restrained Braces under Earthquake Action

Abstract:

The energy dissipation design method has received more attention by engineering circle. Nowadays, the buckling restrained braces (BRBs) are used in higher structures being dissipation energy components. So, it is very necessary to determine the damage quantity of BRBs under earthquake. Firstly, the meaning of the damage quantity of BRBs is clarified based on the energy theory. Secondly, a single degree of freedom analyses model which is suitable to the frame structure is proposed. The nonlinear dynamic time-history analysis of BRBs system is carried out by using FEMS software of ANSYS 11.0 and seismic response of BRBs is obtained. Finally, a practical calculation model of the Damage quantity of BRBs is established. Using MATLAB software, the Damage quantity of BRBs is obtained.
