Abstract:Development of the upper space above the subway is an effective means to improve the urban land ratio. Combining with practical engineering case in Zhengzhou, the problems encountered during the design of the over-track structure above the subway vehicle base and the corresponding treatment methods were mainly expounded. Combining with characteristics of the structural system of the project, performance-based seismic design method was used. Reasonable performance goals were proposed to different components, and programs of YJK, MIDAS Building and PKPM were adopted to carry on the calculation and analysis of the structure under frequent earthquake, fortification earthquake and rare earthquake. Analysis results show that the structural system of this project is safe and feasible, and it can provide reference for similar engineering design.
Keywords:over-building; vehicle base; frame-supported shear wall structure; seismic performance analysis; out-of-code high-rise building
