【摘要】：随着建筑高度的增加,结构的侧向变形和舒适度问题逐渐突出。传统方法通过改进结构体系、提高结构刚度、强度和延性来提高结构抗震和抗风能力,其造价随结构高度的增加成倍增长。为探寻更优的解决思路,结合具体的工程案例,提出安装黏滞阻尼伸臂和黏滞阻尼墙的组合阻尼减震方案。结构分析结果表明,与传统的提高结构刚度方法相比,组合阻尼减震方案具有更好的综合性能。另外,对案例结构阻尼伸臂和阻尼墙的布置位置和参数进行优化分析,得出较优的布置位置和阻尼参数。最后,对结构进行了罕遇地震下的结构响应分析,证明了组合阻尼减震方案的有效性。组合阻尼减震方法可为类似的工程设计提供有益参考。
[Abstract]:With the increase of building height, the lateral deformation and comfort degree of the structure become more and more serious. The traditional method improves the seismic and wind-resistant ability of the structure by improving the structure system, increasing the stiffness, strength and ductility of the structure. The cost increases exponentially with the increase of the height of the structure. In order to find a better way to solve the problem, combined with concrete engineering cases, this paper puts forward a combined damping damping scheme for installing viscous damping extension arm and viscous damping wall. The results of structural analysis show that, Compared with the traditional method of improving the stiffness of the structure, the combined damping and damping scheme has better comprehensive performance. In addition, the location and parameters of the damping extension arm and the damping wall of the case structure are optimized and analyzed. The optimal location and damping parameters are obtained. Finally, the structural response under rare earthquake is analyzed, which proves the effectiveness of the combined damping damping scheme. The combined damping damping method can provide a useful reference for similar engineering design.
