A 48 ft long plate girder is simply supported at the ends and it has a distributed load of 2.6 kip/ft and three concentrated loads of 30 kip at x=12 ft, 24 ft, and 36 ft, as shown below. A designer provided you with a recommendation of using 1"x16" flange plates and 3/8"x63" web plate, as shown below. The girder is constructed from A-36 steel using E60XX electrodes for all welds. a) Draw a shear force diagram and find the maximum shear force in kip. (107.4) (10) b) Draw a moment diagram and find the maximum moment in kipft. (1.469x10 3 ) (10) c) Find the maximum bending stress in ksi. (14.115) (5) d) The flange plates are welded to the web plate on both sides using matching intermittent 5/8" fillet welds. What is the minimal total length of the intermittent welds for each side? (4.088ft) (10) e) Bearing stiffeners that are 0.5"63"7" are used at the left and right end supports. Find the minimum fillet weld size of the weld (in inch) that is required to join the bearing stiffeners to the web plate. (3/16")
