| 摘 要： | 模拟火灾作用,采用大型结构分析程序ANSYS对钢筋混凝土简支梁的温度场进行了非限性有限元分析,得出了火灾作用下混凝土简支梁的温度场分布规律;并将计算结果与试验结果进行了比较,表明温度场的计算结果与实际结果符合良好,从而使火灾作用下钢筋混凝土简支梁的温度场分析从以往的定性分析上升到定量分析,为今后控制火灾作用对钢筋混凝土简支梁的影响提供了重要的计算依据和背景材料.

| Abstract: | The finite element calculation is done on temperature field of reinforced concrete beam under fire hazard load,and the temperature field regularities of reinforced concrete beam under fire hazard load are derived.The calculation result of temperature field is well identical with the experimental result.So,the analysis on temperate field of reinforced concrete beam under fire load is done from qualitative analysis to quantitative analysis,and can supply the important data and material to the engineering supp... |
