准确计算出受火钢筋混凝土构件内温度场随时间变化对于进行结构耐火分析以及评估火灾后结构的损伤是至关重要的 .TFIELD是笔者开发的专门用于混凝土构件内温度场非线性分析和影响参数研究的软件 .本文对TFIELD的功能、构成、采用的数学模型、求解方法及前后处理器作了介绍 (文中给出了一个应用实例 ) ,计算结果与实验数据符合较好
It is very important to calculate accurately the temperature field in the reinforced concrete member under fire over time for analyzing the structure fire resistance and assessing the structural damage after fire.TFIELD is a new method developed by the author for nonlinear analysis and influence of temperature field in concrete members Parametric software.This paper introduces the function, structure, mathematical model, solving method and pre-and-post processor of TFIELD (an application example is given in the article), and the calculated result is in good agreement with the experimental data
