Prying force on bolts
Webb1 okt. 2024 · Prying forces at bolted connections commonly occur in steel structures. The axial force in a bolt is the sum of the pulling and prying forces [1]. Prying forces cause the bearing capacity of a connector to decrease significantly [2], [3], [4]. Studies have shown that prying forces depend on the stiffness of the connecting plate [5], [6]. WebbWith four bolts, the maximum effective length is 2g = 8 in. Thus, there are 4 in. of tee length tributary to each pair of bolts and LRFD ASD 2 bolts(20 kips/bolt) 10.0 kips/in. 4 in. = 2 bolts(13.4 kips/bolt) 6.7 kips/in. 4 in. = The minimum depth WT that can be used is equal to the sum of the weld length plus the weld
