【摘要】 重庆"嘉陵帆影"二期塔楼是一幢高440m,共94层的超高层建筑,按相似关系,对塔楼设计制作了1∶40的试验模型,并对模型进行了振动台试验。研究了结构在7度小震~8度大震下的地震响应,验证了结构的抗震性能。试验结果表明:结构设计能满足规范要求,总体上可达到预设的抗震设计性能目标。更多还原

【Abstract】 The tower building of"Jialingfanying"( phase2) in Chongqing is a 440 m super high-rise building with 94 stories. According to the similitude relation,a 1∶ 40 scaled model is designed,manufactured and tested on the shaking table,the earthquake responses of the model is studied under various seismic actions from 7 degree frequent earthquake to 8 degree rare earthquake,and the seismic performance is verified. The results show that the structure can satisfy the requirements of codes and achieve the target of performancebased seismic design.更多还原
