Abstract：Due to the story drifts of a high-rise frame-corewall structure in high seismic intensity region is beyond the limit, the lead-viscoelastic coupling beam damper (LVCBD) is adopted to control structural vibration in the seismic energy dissipating design. Elastic time history analysis under frequent earthquake and inelastic time-history analysis under rare earthquake respectively by using ETABS and Perform-3D are conducted on the primary structure and damped structure equipped with LVCBDs to investigate the structural seismic response and energy-dissipated capacity of LVCBD. The research results indicate that the LVCBD can be applied in damping design of frame-corewall structure to enhance seismic performance of the whole structure, mitigate or avoid plastic failures of the main structural components, and play first seismic line function, which can protect the safety of main structure in the earthquake.
