摘　　要：对成都中海天府新区超高层项目缩尺比例为1∶40的模型进行振动台试验研究,介绍了试验设计、试验现象以及结果分析。试验测试了结构的动力特性和在不同水准地震作用下的动力响应与损伤情况,分析了结构抗侧力体系在地震作用下的损伤发展程度,评价了其整体抗震性能,并对结构薄弱部位提出设计改进建议。主要试验结果与有限元分析结果吻合程度较好,可互为验证。试验结果表明:成都中海天府新区超高层项目结构设计合理,结构整体抗震性能可以满足预设结构抗震性能设计目标。The shaking table test of the 1∶40 scale model of the super high⁃rise project of Chengdu Zhonghai Tianfu New District was carried out,and the test design,test phenomenon and result analysis were introduced.The dynamic characteristics of the structure was tested,the dynamic response and damage of the structure under different levels of earthquake were also tested.The damage development degree of the structure’s lateral force resistance system under earthquake was analyzed,the overall seismic performance was evaluated,and the design improvement suggestions for the weak parts of the structure were proposed.The main test results agree well with the finite element analysis results,which can be mutually verified.The test results show that the structure design of the super high⁃rise project of Chengdu Zhonghai Tianfu New District is reasonable,and the overall seismic performance of the structure can meet the preset structure seismic performance design objectives.
