Research Progress on Fire Resistance Performance of Beam-column Nodes with Cementitious Grouts
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.
