A channel C250x37 mm section is welded to a 9 mm gusset plate. Welding is not permitted on the back of the channel. All steel is A36 with Fy=250 MPa and Fu=400 MPa. Use E70electrodes having and Fu=485 MPa (SMAW) process. The maximum length of lap is 250mm. The size of fillet weld is 8mm. Assume the width of slot weld is 22 mm. Size of slot weld is 13mm   Properties of C250x37 A = 4750 mm2 tw = 13.0 mm2 d = 254 mm     a. Determine the force resisted by the slot weld in kN, when the full tensile capacity is 712.5 KN (from the gross yielding capacity using ASD)   Hint: Full tensile Capacity = Force Resisted by Fillet and Slot Weld   Round your answer to 3 decimal places.

A C130x10 tension member is welded to a plate as shown in the figure. The channel is of Grade 350W steel. The channel is welded on both sides with 110 mm long fillet weld. Assume the weld does not govern the capacity, calculate the factored tension resistance of the channel. The tension resistance is not governed by the plate. C130 XI0

Please Use LRFD * ASD!

Using SMAW process, E70 electrodes and an A572 steel. Determine the length of the side fillet welds for the full capacity the 125x100x10mm angle tension member as shown below. Assume that the member is subjected to repeated stress variations making any connection eccentricity undesirable. Check the block shear strength of the member. Assume that the WT chord has sufficient strength to develop the weld strengths and the thickness of its web is 12mm. Use U=0.87 for class use and LRFD Method only.
