Control and research of lead shear damper in a typical energy dissipation high-rise structures

To study the lead dampers damping effect in the High-Rise frame-shear wall structures, a High-Rise structure is adopted as engineering background. Firstly, the dynamic performance of the structure is analyzed by SAP2000. Secondly, the energy dissipation suspension design is done in this paper. Finally, the nonlinear finite element analysis software ABAQUS is used to analyze the seismic performance of a High-Rise frame-shear wall structure with lead shear dampers under the action of the rare earthquake and compare the elastic-plastic analysis results under the action of different seismic wave. Analysis results show that the structural seismic performance has been improved significantly, A successful engineering case was provided for the application of lead shear dampers in the damping design of high-rise frame-shear wall structures.
