摘要
重庆中心一期采用框架-核心筒多塔结构。介绍了工程概况和结构体系及布置,针对结构的超限情况提出了相应的抗震加强措施,并采用YJK和MIDAS软件进行了小震、中震作用下的弹性计算及大震作用下的动力弹塑性分析,工程各项计算指标均符合规范要求,可为同类结构的设计提供参考。
The frame core-tube multi-tower structure is used in first-phase project of Chongqing Center.This paper introduces the project profile,the structure system,and the seismic strengthening measures based on the out-of-code high-rise building.By the use of YJK and MIDAS Building for the elastic analysis under frequent earthquakes and moderate earthquake and the dynamic elastic-plastic analysis under rare earthquakes,it has been shown that all the results can satisfy the criteria and specifications.The conclusion can be provided as the reference for the designs of similar structures.
