高強度スタッドボルト摩擦接合継手のスタッドせん断強度に関する研究

抄録

High strength stud bolts (Strength: equivalent F8T or SM570) are welded with the base plate using an arc and are used as frictional joints. It is an issue to determine the mechanical properties of the stud weld depend on the stud bolt or the base plate. Through element tests of the stud bolts, it was found that the mechanical property of the stud weld was determined by the stud bolt. Tensile test of frictional joints showed that the fracture position is the stud weld, and the shear strength of the weld is greater than the shear strength of the stud bolt. In addition, the weld collar has a significant effect on the shear fracture load of the stud weld.
