摘　　要：双层柱面网壳结构体系是解决大跨度场所的主要形式。对于网壳结构设计来说,高冷高热、气温变化是无法回避的问题。温度作用对整个系统和相应的支座会产生变形和较大的应力,如不加以约束,会积累过多的应变进而产生大的次生应力,导致超静定结构变为静定结构甚至发生严重事故。通过以双层柱面网壳结构为研究对象,剖析温度应力为主的多工况作用对壳体关键构件的影响。The double-layer cylindrical reticulated shell structure system is the main form to solve the large-span site. For the design of reticulated shell structure, high temperature, high temperature and temperature change are unavoidable problems. The temperature effect on the whole system and the corresponding support will produce deformation and large stress, if not restricted, will accumulate too much strain and produce large secondary stress, resulting in the statically indeterminate structure into a statically indeterminate structure or even a serious accident. Based on the double layer cylindrical reticulated shell structure, the influence of temperature stress on the key components of shell is analyzed.
