Numerical analysis of initial imperfection influence on the performance of buckling-restrained brace

Abstract: Original scientific paperThe interaction between the core and external restraining members of the buckling-restrained brace (BRB) should be considered because of the significant effect it may cause on the overall performance of BRBs. The mechanism of core member multi-wave deformation is studied for the first time in this research, which presents an actual flexural wave-shape development of core member with increasing axial load and reveals the contact force distribution and development between the core and ex… Show more
