| 摘 要： | 采用复合型铅粘弹性阻尼器对带转换层框肢剪力墙结构的某酒店进行了耗能减震设计，对耗能减震结构和钢支撑结构进行了对比分析，包括反应谱和局部非线性多遇地震作用和罕遇地震作用下的时程分析。结果表明，底部框架结构布置复合型铅粘弹性阻尼器后，在多遇和罕遇地震情况下层间位移能满足《建筑抗震设计规范》要求，并且采用耗能减震结构能优化整体结构，不会对转换层上部结构产生不利的影响，能更好地改善结构的抗震性能。

| Abstract: | A column-shear-wall transfer structure with the mixed lead viscoelastic dampers was designed. The response spectrum analysis and local nonlinear time history analysis in frequently occurred earthquake and seldomly occurred earthquake of the column-shear-wall transfer structure,added with the mixed lead viscoelastic dampers and steel braces of the frame story,are completed. The results show that the inter-story displacement of the structure with energy dissipation devices can meet the seismic performance demands of Code for Seismic Design of Buildings in frequently and seldom occurred earthquakes, and the inter-story displacement and torsional deflection are smaller than the structure with steel braces. Compared with the structure with steel braces, the behavior of the structures upper the transfer story is not influ- enced. Therefore, the seismic behavior of column-shear-wall structure with energy dissipation devices had been obviously improved due to the energy dissipation devices, and turned into multi-defence systems of seismic engineering. |
