摘要

本文采用ABSQUS软件对钢筋混凝土梁柱转换节点加热和冷却全过程的温度场进行了分析。结果表明，模拟温度场的变化趋势与实验相似，测点的最高温度均出现在停火后，且不同测点的温度滞后程度不同。通过对模拟测点温度场与实测测点温度场的比较，发现靠近试件表面的测点温度吻合较好，但试件内部测点温度存在一定差异。

Analysis of the whole process temperature field of RC beam and column transfer joint under fire

In this paper, the ABSQUS soft ware is used to analyze the temperature field of the whole process of heating and cooling of the RC beam column transfer joint. The results show that the variation trend of simulated temperature field is similar to that of the experiment, the highest temperature of the measurement point all appears after cease-fire, and the temperature lag degree of different measurement points is different. By comparing the temperature fields of simulated and measured measuring points, it is found that the temperature of measuring points close to the specimen surface is in good agreement, but the temperature of measuring points inside is different to some extent.
