［摘要］成都来福士广场T4塔楼竖向布置不规则，自下而上存在几处收进，且存在竖向构件不连续、扭转不规则等超限情况。为验证工程设计所采用的计算方法与构造措施是否合理和满足抗震要求，按照相似比关系制作了1∶20的模型，并进行了模拟地震振动台试验。根据试验结果，检验了结构的抗震性能，研究并发现了结构中的薄弱部位，提出了收进位置节点加强等改进措施。［关键词］成都来福士广场; 立面收进; 振动台试验; 抗震性能中图分类号：TU398.7 文献标识码：A 文章编号：1002-848X(2015)13-0039-04
Shaking table test on T4 tower of Raffles City in ChengduTian Chunyu, Liu Junjin, Zhang Hong, Cao Jinzhe(China Academy of Building Research, Beijing 100013, China)Abstract: The T4 tower of Raffles City in Chengdu has irregular vertical arrangement with several setbacks from ground to top floor, and the structure also have out-of-code condition of discontinuous vertical components and irregular torsion. To verify that if the calculation method and structure details were reasonable and satisfied with the requirements of seismic design, shaking table test was carried out on the 1∶20 model which was produced according to the similarity ratio relationship. According to the test results, the seismic performance of the structure was tested, the weak parts of the structure were studied and found out, and measures of node strengthening of the setback position were put forward.Keywords:Raffles City in Chengdu; elevation setback; shaking table test; seismic performance
