Influence of fireproof damage on structural performance of post-installed anchor joint subjected to post-earthquake fire

[摘要] To study explore the influence of post-earthquake fireproof coating damage on structural behaviour of steel-concrete post-installed joint, a three-dimensional FE model has been established by ABAQUS software. Parametric analysis has been carried out and the earthquake level on fireproof coating of post-installed joint by changing thickness of fireproof coating is analyzed under the condition of thermal-force coupling. By damage degree variation of fireproof coating, the influence of fireproof coating damage of anchor plate on fire endurance and bearing capacity of post-installed joint is further analyzed.
