超高层主楼与裙房黏滞阻尼器连接减振分析研究
|
摘要
针对上海世茂国际广场裙房(广场)部分由于刚度与质量分布之间的偏心导致扭转变形突出这一问题,采用CANNY程序对主楼和裙房之间黏滞阻尼器连接减振方法开展一系列非线性时程分析,从裙房变形减振效果、主楼变形影响、阻尼器耗能性能等几个方面综合评定该减振方法的有效性。结果表明,在主楼和裙房(广场)之间采用黏滞阻尼器连接这一方法,不仅能有效地控制因扭转效应过大产生的变形,而且对主楼不会产生不利影响,各阻尼器能在设定的范围正常工作。目前这一减振措施已于2005年成功应用到实际工程中。
The seismic torsional response of the podium structure of the Shanghai Shimao International Plaza is excessively large due to its eccentricity in stiffness and mass distributions. A series of nonlinear time-history analysis are carried out by using the CANNY program to evaluate the reduction method of adopting dampers connecting the podium with the main building. The reduction effect of the podium, the influence on the main building and the dissipative performance of the dampers under different earthquake intensities are analyzed respectively. The results show that using the linking dampers can not only effectively reduce the torsional seismic response of the podium structure, but also have little influence on the seismic performance of main building, and all dampers can function well within the desired scope. The reduction method was already put into use in the year of 2005.
