Abstract: Hangzhou Qingting Park is a multi-tower high-position conjoined structure project with complex shapes andirregularities in plan and vertical. The 10 towers have different stories connected by section steel on the roof and corridorsfloor. The basement has a total of 4 floors and adopt a reinforced concrete frame structure system; the 7# ~ 10# towers onthe ground adopt a steel frame-concentrically-braced structure system; the 1 # ~ 6 # towers adopt a steel frame structuresystem. A variety of structural analysis software was used to calculate and compare the whole structure, and the envelopedesign of the mechanical performance of the multi-tower was carried out. The construction sequence was customized byusing the concept of generalized story, and a reasonable and practical construction sequence was obtained. Theperformance-based seismic design ( PBSD) of the Standards for design of steel structures ( GB 50017—2017) was carriedout, the finite element analysis of the complex steel structure joints was carried out, and the basement and foundationdesign were introduced. The analysis results show that all the indices of the structure satisfied the standards and can meetthe design requirements.

Keywords:Hangzhou Qingting Park; multi-tower high-position conjoined structure; generalized story concept; customizedconstruction sequence; performance-based seismic design; finite element analysis
