摘　　要：武汉世茂锦绣长江A2地块的1-3号超高层住宅楼属超限高层建筑工程。为研究在地震作用下的抗震性能,对其进行了缩尺(1/30)整体模型的振动台试验,研究了模型结构的动力特性以及在6度多遇、6度基本烈度、6度罕遇和7度罕遇地震作用下的动力反应。观察裂缝出现和发展情况,研究结构的破坏形式和破坏机理,指出该结构的薄弱部位,并提出设计改进建议和构造加强措施。The high-rise residential building in A2 block developed by Wuhan Shimao Group is beyond the restriction of the code.To investigate its seismic performance under earthquake,a shaking table test for its 1 /30 scale model was carried out.The dynamic characteristics of the structure and its dynamic responses under different levels of earthquake were studied.Using the shaking table test data and the observed cracking pattern,seismic performance and failure mechanism of tested model were studied.The weakness parts of the structure were investigated and the suggestions and measures to improve the seismic ability were presented.
