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.
