摘要

受火构件内部温度场随时间和空间的变化规律对结构和构件的高温响应和抗火性能是至关重要的。应用通用有限元分析程序ABAQUS

对火灾下钢筋混凝土柱的二维温度场和三维温度场进行了有限元分析计算。所得计算结果与相关试验数据吻合

证明了通过通用有限元软件对钢筋混凝土结构进行三维温度场分析的可行性

也为混凝土结构在高温下以及高温后的三维响应分析提供了理论依据。

Abstract

The spatial and temporal characteristics of temperature field is important for understanding high temperature response and the fire resistance performance of structures and components subjected to fire.In this paper

the 2D and 3D temperature fields of reinforced concrete columns under fire are analyzed using the finite element analysis software ABAQUS.The computational results are well consistent with experimental data.The results show that the finite element method is feasible to analyze the 3D temperature field of concrete structure.This research provides theoretical basis for three-dimensional response analysis of concrete structures at and after the elevated temperature.
