［摘要］   对重庆英利大厦超高层建筑的结构方案进行了分析比较。对复杂风环境中立面弧形收进的建筑进行了风洞试验，确定主楼的风荷载体型系数等设计参数。采用多个程序对结构进行了计算，各项计算指标均满足规范要求。还对整体结构进行了7度罕遇地震作用下的静力弹塑性分析，结果表明，主体结构能够保持较好的工作状态。

Abstract:The structural system of Chongqing Yingli super high-rise building was analyzed. In order to obtain proper design coefficients such as the wind load shape coefficient, the wind tunnel model tests of the building with distorted shape were carried out under complex wind conditions. Different computer programs were used to perform the structure analysis for this building. After meeting all required criteria in the code, the static elasto-plastic behavior of the building under an infrequent earthquake with an intensity of 7 degree was also analyzed. The results show that the main structure has good performance.
Keywords:super high-rise building; structural design scheme; wind tunnel test; nonlinear static analysis method
