You are to choose the appropriate beam for the following loading situation and support that your choice is correct. 3 kips/ft 18 kips 6 ft 3 ft 8 ft Select the lightest Wide Flange (W) beam and the lightest Standard Flange (S) beam; showing the worst case stresses in each beam. Write a brief report that justifies your selection and demonstrates your analysis techniques. 1. Structural members will be selected from Appendix C in the text. Material must be A36 Steel as listed in the text. 2. Factor of Safety for the structure must be 2.0 with respect to yielding in tension or compression and 2.5 with respect to yielding in shear. Approach: Perform a beam design by performing the following steps. 1. Perform the static analysis including a FBD. 2. Draw clear and accurate shear and moment diagrams of the beam with maximums labeled and non- linear curves identified 3. Tentatively select a W and a S beam based on maximum normal stress. 4. Check the tentatively selected beams for maximum shear. 5. Find the principal stresses at the web/flange junction of each beam using Mohr's Circle.
