摘　　要：以广州体育馆钢屋盖结构为例,对大跨度结构使用阶段在日照作用下的温度应力进行了现场连续测试,给出结构的不同构件在日照温差作用下温度应力的数值变化范围和分布规律,测试结果可为同类工程设计和施工提供参考。The continuous measurement of temperature stress caused by sunlight on steel roof truss of the Guangzhou stadium is presented in the paper. And it is given that the scope and distribution of the stress of each kind of components under sunlight temperature action. These results may give a valuable reference to relevant engineering designs and constructions.
