摘要：In order to study the influence of fireproof coating damage after earthquake on the behaviour of post-installed joint at high temperature, the numerical analysis method is adopted to simulate the post-earthquake fire performance of post-installed joint under the action of high temperature. Two parameters are considered in this study, and the high temperature performance and thermal-mechanical coupling performance of model with damage thickness of 5 mm-40 mm and damage length of 100 mm-600 mm be analysed respectively. By observing the temperature change of damage at different positions and the performance of fireproof coating with different damage under the action of temperature field, the temperature of bonded-in rebar is obtained. Finally, the influence of damage length and thickness of damage to the performance of post-installed connection is explored.
