摘要:: 钢——混凝土组合结构是继钢与混凝土结构而兴起的一种新结构类型。组合结构的基本意义是:在一构件中,将型钢与混凝土结构材料密切组合成为一个整体,共同承受荷载。这种结构类型的优点是在大型、高层及重型建筑结构中,较单独采用钢筋混凝土结构有更好的适用性——减小构件体积、增大使用空间和减轻地基荷载、节省木模和支撑,节省混凝土用量,有更好的抗震性能和免除构件中的予埋件。较单独采用钢结构,则大大节省钢料。本文将钢-混凝土组合结构分为柱和梁两个部分,并分别对各种组合柱和组合梁的构造、受力性能、优缺点、适用范围以及国内外发展简况进行评介。

Abstract:: Steel-concrete composite structure is a new type of structure after steel and concrete structure.The basic meaning of composite structure is: in a member, the steel and concrete structural materials are closely combined into a whole, and jointly bear the load.The advantage of this type of structure is that in large, high-rise and heavy building structures, it has better applicability than the reinforced concrete structure alone - reducing the volume of components, increasing the use of space and reducing the foundation load, saving wood forms and supports, saving the amount of concrete, having better seismic performance and eliminating the embedded parts in the components.Compared with the steel structure alone, the steel material is greatly saved.In this paper, the steel-concrete composite structure is divided into two parts, column and beam, and the structure, mechanical performance, advantages and disadvantages, application range and domestic and foreign development of the composite column and beam are reviewed respectively.
