Abstract
As a kind of prospective energy dissipation and vibration reduction component,buckling-restrained brace(BRB) overcomes the buckling characteristics of conventional braces,and behaves nice energy dissipation capacity and ductility under earthquake affection.In this paper,the constitution of the triple-steel tube buckling-restrained brace was introduced,as well as its energy dissipated principle,a FEM analysis of the triple-steel tube buckling-restrained brace by software ANSYS was conducted,and the influence of the gap between the core tube and the restrained tube to the bearing capacity and hysteretic performance of the brace was studied.And the correctness of the finite element analysis was verified by experiment.The result indicate that the simulation analysis of triple-steel tube buckling-restrained brace is feasible by software ANSYS,the operating principle of triple-steel tube buckling-restrained brace is obvious and its have a stable capacity of hysteretic energy dissipation,the gap of brace has a great influence on the energy dissipation capacity and bearing capacity.
