Question

You have begun your first occupation at the structural engineering firm. Your bosses have given you your first task which is relied upon to take you just a couple of days. Be that as it may, they will watch the nature of your work on this task to evaluate your knowlegde and decide your future assignments You are to pick the suitable beam for the following loading situation and demonstrate your decision is right. To impress your superiors, perform a complete beam design by selecting the most efficient beam The material must be A36 Steel, and 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 65 kN 45 kN/m 35 kN/m C E 3 m 3 m 2 m Objectives 1. Draw clear and accurate shear and moment diagrams of the beam 2. Tentatively select a W and S beam based on maximum normal Bending stress. 3. Check the tentatively selected beams for maximum shear 4. Identify the locations on the beam where the shear and moment could possibly combine to exceed the allowable stresses
