| 摘 要： | 用数值计算方法分析了高温下构件的混凝土保护层厚度对主筋力学性能的影响，分析了抗弯刚度与构件经受火灾作用时间的关系，并与实验结果进行了对比。对高温后的构件，研究了构件剩余承载力的计算方法。并从经济和安全角度考虑，对有防火要求的普通混凝土受弯构件，提出了对混凝土保护层厚度取值建议。

| Abstract: | The numerical implementation is used to analyze the effect of the concrete protector thickness to the reinforcement mechanics performance under the high temperature. The relationship between the bending rigidity and the time that the members endure the fire disaster is analyzed and is contrast with the experimental result. The calculation method of residual carrying capacity is studied for the component enduring high temperature. Considering the economy and the security, the propositional value of the concrete protector thickness is suggest for the common concrete flexural member which is required to prevent fire disaster. |
