摘　　要：网架结构广泛应用于体育馆建筑,结构整体一般为混合结构体系,即上部为钢结构网架体系,下部为框架结构或剪力墙结构体系.目前大多数设计将两种体系分开设计,为避免与实际结构的受力差别,在空间网格结构的设计过程中,考虑上下结构的相互作用,从结构的整体性进行结构设计正得到越来越多设计者的重视.本文以一个实际工程为例,对局部三层网架和下部混凝土框架支承结构进行整体建模,验算和完善上下部结构的单独设计,分析思路可为同类工程提供参考.Space grid structure has been widely used in gymnasiums. The overall structure commonly adopts hybrid structural systems, in which roof structures are steel grids, while supporting structures are concrete frame or steel frame. Usually the upper grids and the supporting structure are separately designed. In the design process of space frame structures, cooperating the interaction and overall performance on upper and lower structures are gaining extensive attention by more and more designers, since it can avoid the different load-carrying capability between practical structures caused by separated design. This paper takes an actual project as example. The establishment of the overall modeling about partial triple-layer grids and supporting structure examines and improves the separate design on upper and lower structures. The method can provide reference for the design of similar projects.
