Determine the maximum service load, P, that can be applied if the live load-to-dead load ratio is 2.0. Each component is a PL 3⁄4 x 7 of A242 steel. The weld is a 1⁄2-inch fillet weld, E70 electrode. a. Use LRFD. b. Use ASD.
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.
An I-section bracket is connected to the column as shown. The size of weld is 6 mm on web and 10 mm on flange. What will be the safe load (in kN) that can be carried by
the connection? Assume NA for whole weld = 110.57 x 106 mm4. Use Fe410 grade steel.
