A 1/4-inch fillet weld is used to connect the members shown in the accompanying illustration. Determine the design capacity of this connection assuming E80 electrodes and A572 Gr. 65 steel are used. Also, ensure that the weld meets size limitations. x 12 PL PL를X8 10 in

If the structural frame is replaced to structural steel and the connections is to be designed, determine the following Determine the centroid of the weld measured from the given origin A.   Determine the direct shear load in the welds.   Determine the required size of the fillet weld(E60xx) if the maximum resultant load is 750,000 N/mm

See the image. Two steel plates are welded together. The thickness of the bottom plate is 10mm and the thickness of the top plate is 8mm. What is the maximum and minimum sizes of the weld.

All measurements shown in mm. The connected plates are 10mm. Apply NSCP Specs for welded connections. Fy =420MPa, Fu = 580MPa. L2is the length of the transverse weld. Note: L1 = 500mm, L3 = 500 & width = 300mm. 1. Determine the maximum weld thickness that can be used.2. Determine the effective weld length of each weld if the actual welds used in the connection is 4mm. L2 =300mm.3. If the plates used are 10 mm, determine the tension yielding and rupture capacity. Consider θ = 0°, L2 = 0 and LRFD NSCP 2015.4. If the welds used are 8 mm, determine the weld capacity. Consider θ = 0°, L2 = 300mm. Weld strength, Fw = 485MPa. LRFD.5. If the welds used are 8 mm, determine the weld capacity. Consider θ = 30°, L2 = 0mm. LRFD.

Design calculations for a certain 1/2 in fillet weld show that the effective length required is 7 in. If allowance is made for defects at the ends of the weld, the actual length should be NOT less than  A. 9 in. B. 8 1/2 in C.8 in. D. 7 1/2 in.

A tension member splice is made with 14-inch E70 fillet welds as shown in Figure 5. Each side of the splice is welded as shown. All steel is A36. Determine the maximum service load, P, that can be applied if the live load to dead load ratio is 1.5. Note: Assume that the base metal shear strength is adequate (check the yielding strength for the gross area, fracture strength for the effective net area, weld strength and block shear strength).
