| 中文摘要: |
| 本文利用一维非稳态差分方法分析了火灾温度作用时钢筋混凝土板内部温度场分布，根据混凝土和钢筋在不同温度的本构关系及强度变化，对钢筋混凝土板进行了非线性分析，本文所得的温度场和荷载－挠度曲线计算结果与试验结果吻合较好。 |
| 英文摘要: |
| The temperature distribution in reinforced concrete slab is calculated by finite difference method,and deformation of slab is described based on the constitutive model of concrete and reinforced bar under different temperatures,comparison with experimental results and those of analytical indicated that the method is adequate for fire engineering purposes. |
