Abstract: Guangming New District public service platform with a height of 58.6m is regarded as the symbol architecture of the Shenzhen Guangming New District. The structural system is hybrid inclined support and truss combined transfer frame-shear wall structural system with a transfer span of about 42.5m. Above transfer floor, there are cantilevers on each floor which are supported by inclined columns. The cantilevers are increased by floors and the cantilever on the top has the largest span of 12.6m. The shape of the first floor is a complex surface and the standard floors have several large openings in the middle. In order to fully satisfy architectural functions, different structure schemes were compared to discuss the fulfillment methods of above structural systems. A series of key techniques to realize the special structural system were discussed such as force transfer system analysis, equivalent damping ratio calculation, performance objectives realization, transfer members analysis and temperature stress analysis. Thus the structure has optimum structural arrangement and favorable seismic performance by the premise of meeting standard requirements.
Keywords: inclined support and truss combined transfer structure; equivalent damping ratio of hybrid structure; temperature stress analysis; seismic performance
