【摘要】随着社会和经济的发展,大跨度建筑结构应用越来越广泛,而其中的混合结构已成为一种不可或缺的结构形式。大跨度混合结构自重大、设计难、造价高,合理的结构选型及优化设计十分重要。大型城市商业综合体作为一种典型的大跨度混合结构,其中组合构件运用最多,其相互之间的混合及其与混凝土构件、钢构件等的混合也是最为常见的混合结构形式。本文对几种常见的混合结构形式进行比较分析,研究各自的优缺点及设计要点,为实际工程的结构选型及优化设计提供依据。再结合具体的大跨度混合结构工程实例,通过对其选型比较及优化设计,确定合理的结构方案,继而对选定方案进行构件验算。通过本文的工程实例可以看到,在进行优化设计之后,大跨度混合结构体系取得了不错的效果。随着大跨度混合结构的日益增多,积极探讨大跨度混合结构体系的优化设计,具有明显的社会和经济效益。

【Abstract】 With the development of society and economy, long-span building has been widely used in the world, and hybrid structure es an indispensable structure. 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 plex is a typical long-span hybrid structure, in posite members are used the most, and their mutual mixed structure or other hybrid structure mixed with concrete members and steel members are the mon forms of hybrid structure. In this paper, mon forms of hybrid structure pared, 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 bines with specific project paring 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.
