Because of the difficulty and high cost in long-span hybrid building structure design, a reasonable selection of structural system and optimal design are very important. Large urban commercial complex is a typical long-span hybrid structure, in which composite members are used the most, and their mutual mixed structure or other hybrid structure mixed with concrete members and steel members are the most common forms of hybrid structure. In this paper, several common forms of hybrid structure are compared, and we analyze their advantages, disadvantages and key points of design, providing the basis for selection of structural system and optimal design for actual project. In addition, this paper combines with specific project by comparing their selection of structural system and optimal design, and determines a reasonable structure, then conductes member checking for the selected program. Through this project, we can see, structural optimization achieves a good result. With the long-span hybrid structure growing, its optimal design has obvious social and economic benefits. 【Keyword】 building; hybrid structure ; selection analysis; optimal design 大跨度混合结构分析及优化设计 学生 专业: 土木工程 指导教师 袁聚云单位: 土木工程学院地下工程系 赵昕单位: 同济大学建筑设计研究院 【设计总说明】 。主要由一幢超高层建筑（45层）、三幢高层建筑（30层）及其4层裙楼和6幢三层建筑物组成地上总建筑面积约2537万平方米。超高层建筑高层建筑 本次工程的设计依据主要有： 《建筑结构荷载规范》GB50009-2012 （2）《建筑工程抗震设防分类标准》GB50223-2008 （3）《建筑抗震设计规范》GB50011-2010 （4）《建筑地基基础设计规范》GB50007-2002 （5）《建筑桩基础技术规范》J
