【提要】 溫度作用是建筑結(jié)構(gòu)中不可忽略而容易被忽略的問題，其造成的事故往往破壞性較大。對一起由溫度作用造成結(jié)構(gòu)失效的典型案例進行了剖析，描述了結(jié)構(gòu)的破壞特點，闡述了混凝土和鋼材在高溫下的性能差異。該結(jié)構(gòu)破壞的原因是忽略了高溫的影響。在分析的基礎(chǔ)上，提出了合理的解決方案，并提出解決溫度作用的設(shè)計思路。

Research and Project on a Representative Case of Temperature Effect/Luo Guoquan（Department of Civil Engineering，Shanghai Jiaotong University，Shanghai 200030，China）
Abstract:Temperature effect couldn"t be ignored but is often ignored in engineering. The accidents induced by the temperature effect are often serious. A representative case is analyzed. The characteristics of the structure wrecked are described and the different capability of concrete and steel in the status of high temperature is expounded. The analysis shows that ignoring temperature is the reason of the structure breakage. A reasonable solve project is suggested.
Keywords:temperature effect；solve project；restriction condition；free node
