STUDY ON THE DESIGN OF ARC WELD RING PEGS BASED ON HOT SPOT STRESSES
In the common application of steel-concrete structures,the fatigue performance of bolts as their connec-tors has attracted much attention,especially the stress concentration effect at weld toes.A new type of arc weld ring is designed based on the hot spot stress method,in which the height,width,and chamfer of the weld ring are paramet-rically analyzed by ABAQUS and using linear extrapolation for four different diameter pins.The results show that the hot spot stress at the toe of the spigot decreases with the increase of the height(width)of the weld ring and the de-crease of the chamfer.Increasing the height(width)of the weld ring and reducing the chamfer of the ring reduce the stress concentration effect at the toe.
