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。 Chengdu Raffles City T4 tower vertically arranged irregular, there are several bottom-up income, and there is vertical component discontinuity, irregular torsion and so on. In order to verify whether the calculation methods and structural measures adopted in engineering design are reasonable and the seismic requirements are met, a 1:20 model was made according to the similarity ratio and the shaking table test was simulated. According to the test results, the seismic performance of the structure is tested, the weak parts in the structure are studied and found, and the improvement measures such as strengthening the node at the receiving position are proposed.
