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.
