Shear lag in steel angles: An investigation of the South African standards

The shear lag effects on welded steel single angle tension members

“…T r = φA g F y (9) T r = 0.85φA ne F u (10) where T r is the factored tensile resistance; φ is the resistance factor; A g is the gross cross-sectional area and A ne is the effective net area reduced for shear lag. A rather comprehensive approach is adopted by CAN/CSA-S16-01 [4] to evaluate the effective net sectional area in order to account for the shear lag effect.…”

“…Uzoegbo [9] concluded that the shear lag effect should be evaluated individually for each leg of the angle specimen based on his test results for steel angles with welded connections. Petretta [10] tested 23 double angle specimens with welded end connections.…”

An experimental and numerical study of square and rectangular slotted HSS connections

“…of the longest weld Uzoegbo (1998). also conducted a series of tension tests on a single angle welded to the gusset plate at one leg.…”

A study on slotted square and rectangular hollow structural section connections

“…The maximum net section efficiency was found to be greater than 0.9 for plates, 0.8 for angles and a maximum o f 0.9 for channels. Based on the test results, an upper net section efficiency limit for (2.22) o f 0.9 was recommended for most structural shapes Uzoegbo (1998). also conducted a series o f tension tests on a single angle welded to a gusset plate at one leg.…”
