［摘要］复合型铅黏弹性阻尼器是综合利用多种耗能机制的新型阻尼器，针对其在结构中的模拟及减震性能的把握是实际设计应用中的关键问题。结合某4层框架减震实例，通过对设置复合型铅黏弹性阻尼器减震结构在多遇地震和罕遇地震作用下的动力时程分析，考察了阻尼器在减震结构中的耗能表现及减震效果。结果表明，复合型铅黏弹性阻尼器用于钢筋混凝土框架结构中可有效提高整体结构的抗震性能，并能减缓或避免主体结构构件的塑性破坏，保护主体结构的安全，实现结构“强柱弱梁”的屈服机制。

Abstract:The composite lead-viscoelastic damper (CLVD) is a novel damper with multiple energy-dissipated systems, and researches on its simulation and damping effects in real structure have become the key issues in its practical application. A four-storey reinforce concrete (RC) frame was introduced as case study, and dynamic time-history analysis of the damped frame equipped with CLVDs was conducted under frequently-occurred earthquake and rarely-occurred earthquake, so as to investigate the energy-dissipated capacity of dampers and the vibration-control effect of the damped frame. The research results indicate that the CLVD can be applied in  RC frame to enhance seismic performance of the whole structure, and also mitigate or avoid plastic failures of the main structural components, so that the major structure can be safe  and the desirable yielding mechanism of “strong-column-weak-beam” can be achieved.

Keywords:composite lead-viscoelastic damper; energy dissipation; seismic performance; yielding mechanism
