Abstract:The project above Xing Shanzi Metro Depot in Xuzhou is a typical subway cover project, which adopts shear wall structural system in upper residential buildings above the metro depot and frame structural system in bottom part. The project has the characteristics of complex structural system, many types of components, multi towers, and large chassis and so on. The isolation technology is adopted in the design, and thick plate transferred to upper structure in the garage floor. The structure was analyzed under the action of various horizontal loads such as wind load and frequent earthquake, fortification earthquake and rare earthquake, so as to ensure that the structure met the design performance target requirements, and the special analyses were conducted on the thick plate transition and structural elastic-plastic performance. The results show that all indexes of the structure meet the requirements.
Keywords:seismic isolation design; thick plate transition; multi-tower; performance-based design; lead rubber bearing
