［摘要］小米移动互联网产业园主体结构形式采用框架-剪力墙结构，连体部分采用钢结构。由于该工程存在扭转不规则、竖向构件不连续、连体、结构局部转换等超限项，因此工程采用性能化的抗震设计方法，按多个软件计算校核，计算结果按多个模型分别计算并采用包络设计，且提出详细的设计措施。对连体结构的强度、支座位移、两侧楼板应力、舒适度以及转换结构的承载力、墙肢拉应力等进行分析，使其能够实现预设的抗震性能目标。采用天然地基变厚度平板式筏形基础加抗浮桩方案，有效控制基础各部分的沉降差异。

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
