Abstract:The main structure of Xiaomi Mobile Internet Industrial Park adopts frame-shear wall structure, and the conjoined part adopts steel structure. Due to the existence of the exceeded over-limit items of this project, which including torsional irregularity, discontinuous of vertical members, conjoined structure, partial structural transformation, and etc., a performance-based seismic design method and the calculation is checked by multiple programs was adopted for the project. The calculation results were calculated by multiple models and envelope design was adopted, and detailed design measures were proposed. The strength of the conjoined structure, the displacement of the support, the stress of both sides of the floor, the comfort, the bearing capacity of the conversion structure and the tensile stress of the wall were analyzed to achieve the preset seismic performance goals. The settlement difference of each part of the foundation was effectively controlled by using the natural foundation variable thickness flat raft foundation plus anti-floating pile scheme.
Keywords:Xiaomi Mobile Internet Industrial Park； performance-based seismic design； conjoined structure； structural transformation； static elastoplastic analysis
