A 76 mm x 76mm x 6mm angular section is welded to a gusset plate having a thickness of 8mm as shown in the figure. The length L1 equals 125mm and L2 is 65mm. The angular section has a cross sectional area of 929mm2, Fy=248 MPa, Fu=400MPa.
Determine the value of the tensile force P based on gross area in kN.
Determine the value of tensile force P based on block shear in gusset plate along the weld in kN.
Determine the value of tensile force P (kN) based on net area if the value of shear lag factor is 0.85.
