| 中文摘要: |
| 本文利用有限差分法分析了火灾时钢筋混凝土板内最高温度分布，并根据有关火灾温度后钢筋与混凝土的本构关系及钢筋混凝土结构理论，用数值方法计算了钢筋混凝土板灾后承载能力。此外还根据结构可靠度理论分析了钢筋混凝土板在承受原设计荷载时其可靠指标的变化。 |
| 英文摘要: |
| The maximum temperature distribution in reinforced conrete slab is determined during fire by finite difference method,and the residual load-bearing Capacity is calculated based on the constitutive relationship of reinforced bar and concrete post fire,meanwhile the relebility Index in analyzed. |
