摘　　要：介绍了温度荷载的类型和各国规范对温度作用的规定,利用有限元分析软件SAP2000计算了某大型火力发电厂支架结构在四种不同支座条件下的温度作用,分析了不同支座对该结构温度作用的影响,提出了有利于释放该结构温度作用的支座形式。Kinds of temperature load and temperature action prescribed in criteria are introduced.Temperature action of support structure of a large-scale thermal power plant is calculated by FEM analysis software SAP2000 in four different supporting blocks.Influence of supporting blocks on temperature action of the structure is analyzed. A supporting block to advantageously release temperature action of the structure is presented.
