摘要
以高烈度区新疆乌鲁木齐市的一栋95.95m高的建筑为工程背景,提出了黏滞阻尼墙减震体系的设防目标,并给出了减震分析的详细流程及阻尼墙的基本布置原则。通过对减震体系的非线性地震响应分析,优化了黏滞阻尼墙的布置,在此基础上详细分析了减震体系的地震作用剪力、位移、能量耗散、附加阻尼比及构件在罕遇地震下的损伤等问题,最后对减震体系的经济性进行了比较。分析表明:黏滞阻尼墙对高层建筑的抗震性能有很大的改善,能够给结构提供额外的附加阻尼比。
The viscous damper walls were adopted indesigning an office building with a height of 95.95 meters,in the high seismic intensity city Urumqi,Xinjiang province.Detailed damping analysis process and basic arrangement principles of damping walls were provided.Through non-linear seismic response analysis of damping system,initial arrangement scheme of damping wall wasoptimized.With regard to this optimized scheme,damping system was analyzed into detail about its seismic force,displacement,energy dissipation,acceleration response,additional damping ratio and plastic transformation order of components.Finally,the economic comparison of damping system was analyzed.
