双层双曲抛物面同壳具有受力合理、刚度好、经济、美观且施工较方便等优点,是一种值得大力推广的大跨空间结构.本文介绍了龙江体育馆屋盖网壳设计(包括结构方案选择,网壳的静、动力分析,温度应力,节点构造),简述了试验情况,提出了防火及施工安装中应重视的问题. The double-layer hyperbolic parabolic shell has the advantages of reasonable force, good rigidity, economy, beautiful appearance and convenient construction. It is a large-span space structure that is worthy of promotion. This article describes the design of the reticulated shell of the Longjiang Stadium. Structural scheme selection, static and dynamic analysis of reticulated shells, temperature stress, nodal structure), brief description of the test situation, put forward problems that should be emphasized in fire protection and construction installation.
