The uniform load includes an allowance for the weight of the beam. The allowable stresses in bending and shear are 18 ksi and 11 ksi, respectively. Select from Table E-2, Appendix E, the lightest I-beam ( S shape) that will support the given loads. Hint: Select a beam based upon the bending stress and then calculate the maximum shear stress. If the beam is overstressed in shear, select a heavier beam and repeat. C P = 3000 lb q = 1200 lb/ft 12 ft 4 ft 8 ft A-PDF Split DEMO : Purchase from www.A-PDF.com to remove the watermark...
