摘要
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 ) 。
In this paper ,a software package TFIELD developed for the nonlinear transient temperature field analysis and parametric studies using the finite element method and the finite difference method is introduced.Detailed descriptions of mathematical model,preprocessors,and postprocessors of TFIELD are given.TFIELD is validated against data from experimental tests.Very good agreement is obtained between the computed and the experimental results.One example is presented.
