摘　　要： 将新型复合式金属阻尼器应用于某高层剪力墙实际工程结构。采用Perform-3D建立了结构的三维精细化非线性有限元模型,通过对结构在9度大震下的弹塑性分析,研究了该复合式金属阻尼器对高层剪力墙实际工程结构的减震控制效果。分析结果表明:加设复合式金属阻尼器后结构的耗能性能明显改善,结构的基底剪力减小20%以上,该复合式金属阻尼器在实际工程中具有良好的推广实用意义。 Application of composite metal damper in seismic control of a real high-rise shear wall building struc- ture is presented. A three-dimensional refined finite element model for the high-rise shear wall building is es- tablished using commercial software Perform-3D. A new energy dissipation device, namely composite metal damper, is employed in the high-rise shear wall building. Nonlinear time history analysis of the high-rise building with composite metal dampers is conducted to investigate the performance of the novel metal damper. Numerical simulation results show that the composite metal damper can greatly increase the additional damping level of the building structure, and the base shear of the high-rise shear building can be reduced over 20%. The composite metal damper is important in practical engineering.
