摘要：
Based on a damage concentrated model, a rocking wall frame (RWF) structure system with buckling-restrained braces (BRBs) in base was put forward to reduce the displacement response of RWF under a strong earthquake and mitigate the damage concentration effect of a buckling-restrained braced frame (BRBF). Taking a 9-storey steel frame as the benchmark model, pushover analysis and dynamic time history analysis were conducted to comparatively study its aseismic performance. The results showed that before BRBs yield, this structure is similar to the shear wall frame (SWF), the additional lateral stiffness is provided by BRBs and transferred through the rocking wall; after BRBs yield, the structure tends to rock, the rocking wall controls the lateral deformation mode and BRBs consume seismic energy to lead to full use of the aseismic capacity of each part. © 2016, Editorial Office of Journal of Vibration and Shock.
