超长框架结构冷库温度作用及结构设计探析

Analysis on temperature effect and structural design of super long frame structure cold storage

冷库是一种特殊的仓储类建筑具有内冷外热、结构用材要求高及冷桥问题突出等特点。悬殊的室内外温差导致温度作用,对冷库影响不可忽略。结合实际工程,首先梳理了冷库温度伸缩缝设置和结构体系选择情况,然后对冷库温度作用进行着重分析。针对冷库温度作用明显的问题,并对温度荷载计算、温度计算参数选取,以及温度计算结果分析进行探讨。通过探讨,总结温度作用对冷库结构的影响规律,以及冷库各项抗温度措施,减少温度作用对冷库所带来的不利影响。

Cold storage is a special kind of storage building with the characteristics of cold-inside and hot-ouside, high structural material requirements and outstanding cold bridge problems.The difference between indoor and outdoor temperature leads to the temperature effect, which can not be ignored on cold storage.Combined with the actual project, first of all, the cold storage temperature expansion joint setting and structural system selection, and then the cold storage temperature effect is emphatically analyzed.In view of the obvious effect of temperature on cold storage, the calculation of temperature load, the selection of temperature calculation parameters and the analysis of temperature calculation results are discussed.Through discussion, the influence law of temperature effect on the structure of cold storage is summarized, and the anti-temperature measures of cold storage are taken to reduce the adverse effect of temperature effect on cold storage.
