摘要
为了研究剪切型铅阻尼器在高层建筑结构中的耗能减震效果,以高烈度地区某设置剪切型铅阻尼器的框架-剪力墙结构为工程背景,首先通过Sap2000分析了结构的动力特性,在此基础上对结构进行了消能减震设计。其次采用非线性分析软件ABAQUS对结构进行了罕遇地震作用下的有限元分析,对比了不同地震波作用下的结构弹塑性分析结果。分析结果表明:设置剪切型铅阻尼器的高层建筑结构的抗震性能较好,为剪切型铅阻尼器在高层框架-剪力墙结构中的应用提供了成功的工程案例,其设计思路可以为高层结构的减震提供有益的借鉴和参考。
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. 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.
