Technical Field

The earthquake-resistant performance of the structure is considered in the building built in the earthquake area. In the use process of a steel structure or a reinforced concrete structure, the common support is pressed to generate a buckling phenomenon, and when the support is pressed to buckle, the rigidity and the bearing capacity are sharply reduced. Under the action of earthquake or wind, the internal force of the support changes reciprocally under the two states of compression and tension. When the support gradually changes from a buckling state to a tension state, the internal force and the rigidity of the support are close to zero. Therefore, the hysteresis performance of the common support under the repeated load effect is poor.
The frame buckling restrained brace system has been used as a new form of anti-lateral force system for high-rise buildings in recent years. The application of the buckling restrained brace solves the problem of insufficient overall lateral stiffness caused by buckling of the traditional support system compression brace, but the traditional buckling restrained brace is larger in yield displacement, and when the traditional buckling restrained brace is arranged in a concrete structure or a steel-concrete mixed structure, the traditional buckling restrained brace is difficult to firstly yield and dissipate seismic energy before a concrete member cracks. In addition, in practical application, the conventional buckling restrained brace has a certain problem: (1) The buckling restrained brace has tension-compression asymmetry on the stress performance, mainly because of the participation of the external restraint component, the bearing capacity of the core yielding component is increased; (2) Localized buckling is likely to occur in the neck (unconstrained portion) of the core yield member, resulting in failure of the buckling restrained brace.
