Abstract： To improve the stabilityof prefabricated buildings，experimental research on the mechanical properties of welded ste bartrusses insteestructure prefabricated buildings is designed.Firstly，establishabeamcolumn model for prefabricated steel structures.Then，specimens of D5，D6，and D8 types of trussmaterials were prepared.Finally， place the 1～6 steel bar test blocks into the press for testing，and record the real-time readings and deformation of the steel bartest blocks during the testing process.The simulation experiment results show that under the condition of equal height in prefabricated buildings，buildings with D8 steel structuresteel barsas trusses have stronger stability andcompressionresistance，indicating that in large-span construction，the higher the mechanical performance level of welded steel bar truss structures，the stronger the stability ability of prefabricated buildings.

Keywords： prefabricated buildings; large span stee structures; welded steel bar truss; mechanical properties; beam column model; mechanical node library
