| 摘 要： | 为了考察火灾作用下简支钢梁的破坏特征及结构性能,对2根采用国产轧制H型钢的简支梁在不同荷载水平作用下的抗火性能进行了试验研究.采用水平燃油炉对试件进行升温,给出了采用轧制H型钢的简支梁在火灾作用下的变形和截面温度分布.试验结果表明:在火灾作用下,荷载对简支梁的挠度影响较小,对梁破坏时的温度影响较大.试验结果为H型钢梁火灾行为的理论研究提供了依据.

| Abstract: | To investigate the failure mode and structural characteristics of simple supported steel beams subjected to fire,an experimental research was carried out on two specimens composed of domestic H-shaped steel under different loading levels.The specimen temperature was elevated by the horizontal furnace with oil burner.The deformation and temperature distribution of simple supported steel beams were detected.The results show that loading level has only a little influence on beam deflection but a remarkable influence on the failure temperature.The investigation provides a basis for the theoretical research of the behavior of steel beams under fire. |
