Abstract

Through the pseudo-static test on the steel truss coupling beams with buckling-restrained brace, the bearing capacity, deformation capacity, hysteresis curve, skeleton curve, ductility, Energy Dissipation and stiffness degradation of such coupling beam are understood. The test results show that the steel truss coupling beams with buckling-restrained brace is characterized by bigger bearing capacity, higher ductility and good plastic energy dissipation capacity.

Keywords: Buckling-restrained brace, ductility, energy dissipation, steel truss coupling beams.
