Abstract

Abstract

To study the properties of fracturing at the weld of cover plate reinforced joint, 3 local specimens of cover plate reinforce connection were tested under uniaxial tensile loading and analyzed by finite element model. The influence of thickness of cover plate and the material strength on fracture properties were studied. The results showed that the failure modes of the specimens could mainly be divided into two types; namely fracture of beam flange and fillet weld fracture at end of cover plate; when the cover-plate was thicker, the risk of cracking at weld increased; when the thickness of plate reached a certain value, the change of thickness had little effect on the bearing capacity of the specimen and the fracture performance of the weld; increasing the strength of the material could improve the bearing capacity of the specimen and reduce the plastic deformation capacity of the specimen, but had no obvious effect on the fracture properties of the weld; the fillet weld at the end of the cover plate had a higher risk of cracking than butt weld.
