Abstract:Tower A of Qingdao Zhejiang Chamber of Commerce International Project adopts reinforced concrete tube-in-tube structure system, with  structural height of 220-75m. The characteristics and out-of-code circumstances of the structure were introduced. Considering the out-of-code conditions，corresponding seismic measures were proposed to ensure the safety, reliability and economic rationality of the overall structure. Multiple kinds of software were used to calculate and analyze the structure performance under frequent earthquake, fortification earthquake and rare earthquake. Supplementary checking analysis were conducted on significant members，such as inclined column, slab of special floor and key joints of transfer truss. The results show that specific strengthening measures proposed are safe and effective, andthe designed seismic performance objective of “three levels” can be achieved.

Keywords:super-rise building; transfer truss; inclined column; performance-based seismic design
