Study on the Seismic Performance of Long-span Steel Truss-concrete-filled Steel Tubular Column Joints
In order to explore the seismic performance of large-span steel truss steel tube concrete column joints,this article takes a public building as an example,establishes a node model for its large-span steel truss steel tube concrete column,introduces a self balancing loading device,and conducts seismic performance research experiments on the model.The results show that the node exhibits good plastic development ability during the stress process,and the overall bearing capacity of the node does not suddenly disappear due to the cracking of the weld seam between the tension web flange and the vertical stiffening rib of the square tube concrete,ensuring the conclusion of complex node stiffness and strength;The large-span steel truss steel tube concrete column joint has good seismic performance,which can promote the improvement of safety and stability of large-span structures in public buildings.
