Abstract

To study the mechanical behavior of tube column and H beam welded joint with Q460 high strength steel (HSS) under earthquake, 11 specimens consisting of flange plate of H-shaped beams that were welded to rectangular columns at flange plates were tested under a cyclic tensile condition. The effects of the width ratio of the beam flange plate to the tube column, thickness ratio of the tube column on the failure mode, bearing capacity, ductility and energy dissipation capacity of the joint are studied. The results show that the failure modes of the tube column and H beam welded joint using Q460 HSS are mainly divided into three types after the cyclic tensile test: weld fracture at the connection, fracture failure of the tube column panel at the connection or tensile fracture of the beam flange; The width ratio α and the width thickness ratio λ have a greater impact on the mechanical behavior of welded joints with HSS, when α decreases from 25.0 to 18.75, the strain energy of the joint decreases by 134%; In addition, when a joint was damaged, the ultimate displacement of a welded joint with a new type of welded access hole construction is nearly two times greater than that of a traditional construction joint, and the former has better ductility. The research results can provide a basis for seismic design and further theoretical research of tube column and H beam welded joint with HSS.
