Simple beam connections in combined shear and tension

Single-angle all-bolted shear connections

“…13) have an impact on the shear resistance of the bolts at the outstanding leg. To address this concern, assuming a uniform distribution of T y along angle length, we have M p = T y L 2 /2 or T y = 2M p /L 2 (10) where the moment is summed up about the lower end of the angle. Then, the tension force for one bolt at the outstanding leg is estimated as (11) where s is bolt pitch and s = 76 mm for this study.…”

“…Their study illustrated that the eccentricity effect on the bolt group at the web-framing leg could be ignored for the welded-bolted connections. Recently, Guravich and Dawe [10] tested the welded-bolted single-angle connections under a combined shear and tension action. Literature review revealed that little experimental study has ever been reported for all-bolted single-angle connections since Lipson [7].…”

Integrity of Bolted Angle Connections Subjected to Simulated Column Removal

“…Guravich and Dawe (2006) tested 108 full-scale connections under combined loading. Their tests were not intended to be representative of column removal, but were rather designed to measure the tension capacity of connections in combination with a nominal 0.03 radians of rotation and large shear forces.…”

Re-examination of double-angle knife shear connections

“…Indeed, Henderson [5] stated that "corresponding experimental evidence is not available for a pair of welded header angles…". Guravich and Dawe [6] tested seven standard knife connections with an angle length of either 150 mm (2 bolts) or 230 mm (3 bolts). They found that the average test strength of the welds was 0.95 times the strength predicted by the Canadian method but 1.44 times the strength by the U.S. method.…”

“…The study showed that the connections possessed a rotational capacity not less than 0.03 rad. Both studies [6,7] observed that the rupture of the welds always started at the top (instead of the bottom) and developed down the welds to cause failure of the connections. McMullin and Astaneh [8] also tested four standard knife connections.…”
