摘　　要：采用水泥灌浆料可广泛用于住宅建筑装配式梁柱节点核心区,既有效提高结构承载力,又有效控制发生火灾时的耐火极限.综述相关学者研究,材料尺寸、荷载参数、材料参数是影响装配式梁柱节点抗火性能的主要因素,对结构节点处的耐火极限、承载力和变形产生巨大影响,节点临界温度点是造成梁柱节点破坏的关键因素.The utilization of cement grout material is a highly versatile technique,particularly in the context of residential building construction.Its application in the core area of assembled beam-column nodes can significantly enhance the structural bearing capacity,while simultaneously ensuring effective control of the fire resistance limit in the event of fire.A review of the literature reveals that the material size model,loading parameters and material parameters are the primary factors influencing the fire resistance of assembled beam-column nodes.These factors have a significant impact on the fire resistance limit,bearing capacity and deformation at the structural nodes.Additionally,the node critical temperature point is identified as a crucial factor in the destruction of beam-column nodes.
