Students have asked these similar questions
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.
Tension Member Design
Problem 1. A channel shape is under 50 kips dead and 100 kips live tensile axial load as shown in the
figure. The member is connected to a gusset plate with 10 inch longitudinal welds. Find the lightest
channel shape to carry the loading. Use only vielding and rupture limit states to design. Use 50 ksi steel
(Fy=50 ksi, Fu=65 ksi).
(a) Assume yielding limit state controls in the design process;
(b) After selecting the lightest section, check the rupture limit state. Do not redesing if needed.
