文摘

Recently, the capacity of welded joints made of direct-quenched ultra-high-strength steel (with nominal yield strength of 960 MPa) has been increasingly investigated. However, less attention has been paid to joints subjected to shear loading. In this research, work the punching shear capacity of a plated structure was studied. The effects of cold forming and welding were also included in the study. The capacities based on analytical calculations were compared with experimental results and values obtained by FEA. The results matched each other quite well. The experimental results proved that if the heat input is moderate the welding alone has only a small effect on the punching shear capacity. However, the heat input together with cold forming seems to decrease the load carrying capacity more significantly.
