Numerical simulation of hysteretic performance of disc spring self-centering system buckling-restrained brace
In order to study the hysteretic performance of the disc spring self-centering system buckling-restrained brace(SC-BRB),the finite element simulation is analyzed by using Abaqus,and the hysteretic performance of the support is carried out.The accuracy of the finite element model is verified by referring to the relevant experiments and theoretical analysis models.The results show that the hysteretic curve of SC-BRB presents a significant"flag"characteristic and has good restoring effect,and the higher initial preload of the disc spring,the more effective resetting action of the support.
