A single unequal angle 100 x 75 x 6 mm is connected to a 8 mm thick gusset plate at the ends by 4 mm welds as shown in Fig. 17. The average length of the weld is 225 mm. Determine the design tensile strength of the angle if the gusset is connected to the 100 mm leg. The yield strength and ultimate strength of the steel used are 250 MPa and 400 MPa. 4 mm, weld Cz= 30.1 I 100 4 mm, werd 8 Fig. 17 Details of connection at end 100 x 75 x 8 75
