| 摘 要： | 应用有限元方法,对火灾下钢筋混凝土连续梁进行了非线性数值分析。通过计算,得到了5种典型工况下的三跨钢筋混凝土连续梁的混凝土与钢筋的应力以及梁的变形、位移。并通过分析可知:高温下连续梁温度荷载与结构荷载类似,在连续梁结构中存在着荷载最不利位置。 |
| 关 键 词： | 钢筋混凝土 连续梁 应力 位移 |

| Abstract: | The continuous beam of reinforced concrete under fire is analyzed by using nolinear finite element method.Through five tipical condition analysis,the stress and displacement of the three-span continuous beam of reinforced concrete are figure out.The result shows that the temperature load is similar to the structural load in continuous beams of reinforced concrete which has a most disadvantageous position. |
| Keywords: | Reinforced concrete Continuous beam Stress Displacement |
