Damage Concentration Effect of Multistory Buckling-Restrained Braced Frames by Hanqin Wang, Yulong Feng, Jing Wu, Qing Jiang, Xun Chong

“…Due to the low postyield stiffness of buckling-restrained braces (BRBs), multistory buckling-restrained braced frames (BRBFs) subjected to earthquakes are prone to lateral deformations and damage concentrations at certain stories, which is deemed a damage concentration effect (DCE). A series of nonlinear pushover analyses and response history analyses are conducted to investigate the key factors affecting the DCE of BRBFs. …”
