Abstract
The Tianjin CTF Finance Center Tower is 530 m in height.It has CFST (SRC) frame-core tube structural system with steep brace and belt truss.The tower is complicated due to its super height,discontinuity of local slab,and irregularity in vertical direction.The overall calculation and elastic time-history analysis have been conducted using SATWE and ETABS software.And the dynamic elastic-plastic time-history analysis in rare earthquake situation is also analyzed using ABAQUS software.Based on the results and concept design,the critical structural elements and locations are strengthened,and the performance-based design in moderate and rare earthquake situation is adopted for critical structural elements.The results show that all indexes meet the code requirements,and performance targets can be achieved.Also the safety,reliability,economy and rationality of structure are verified.The structure system,strengthening measures and joint details of this tower can provide a reference for similar projects.关键词
