近年来多层大跨建筑日益增多,根据需要,中国建筑科学研究院和河南省建筑设计院等单位对多层大跨建筑组合网架结构进行了理论分析、试验研究和工程实践工作,并在新乡百货大楼加层改造工程中加以应用。该百货大楼由两层增加为六层,屋顶为露天娱乐场地。建筑面积由原来的2000m~2增加到10370m~2。在改建工程中采用四层组合网架结构。在上部网架结构施工中,原百货大楼照常营业。

In recent years, multi-storey and large-span buildings have been increasing. According to needs, the Chinese Academy of Building Research and Henan Provincial Architectural Design Institute have conducted theoretical analysis, experimental research, and engineering practice on multi-story large-span architectural composite grid structures. The Xinxiang Department Store will be applied in the addition of the renovation project. The department store has been increased from two floors to six floors and the roof is an open-air entertainment venue. The building area increased from the original 2000m~2 to 10370m~2. In the reconstruction project, a four-layer composite grid structure was adopted. In the construction of the upper grid structure, the original department store is open as usual.
