摘要
本文根据火灾下钢筋混凝土结构的特点以及火灾温度和时间的对数关系，经过合理简化给出了钢筋混凝土结构非线性瞬态问题的计算方法，并用试验予以验证。结果表明，本文给出的计算方法简单、灵活、稳定性好，精度满足要求，可用于钢筋混凝土结构的温度场分析和计算。
Based on the behaviour of reinforced concrete structure exposed to fire and a given (e.g. ISO ) temperature-time curve, the tempersture field of a reinforced concrete structure is considered as a non-linear transient thermal transfer Problem. and a calculation method of 2-D finite element analysis is presented under reasonable simplification. Corresponding computer program is compiled and implemented. The theoretical temperature field of the reinforced concrete member is presented and compared with experimental results. It is found that the calculation method is simple, reliable, accurate and amble. It is applicable to the analysis and calculation of temperature field of reinforced concrete structure.
