Abstract:Wanhua Chemical Research Center Project located in Shanghai is a complex high-rise building composed of six connected towers. Each single tower has multiple out-of-code problems such as complex shape, vertical lateral-resistant member discontinuousness and lateral stiffness irregularity. In addition, towers are connected by skybridges between these towers at different floors and skybridges adopt weakly connected form. The overall cantilever length of the building above the podium is 13-5m at the farthest end, and large cantilever part adopts steel rod suspension structural scheme. According to the engineering characteristics and out-of-code conditions, the performance-based seismic design goals of the structure were determined. Elastic analysis under frequent earthquake, elastic time-history analysis, and pushover analysis were carried out, and the steel rod suspension structure and skybridges were analyzed and designed. The analysis result shows that all the indicators of the whole structure meet the demands of codes and the structural performance condition meet perfectly performance-based seismic design goals.
Keywords:complex high-rise building; multi-tower; suspension structure; weakly connected structure; performance design
