Problem 4: Design a rectangular section for the beam, loads, and p values shown. Beam weights are not included in the given loads. Use h = main_span/8, and b = h/2 to get initial guess for self- weight (you will refine dimensions later using the design aids). When dealing with beams with more than one span, live loads are to be placed where they cause the most severe conditions within the section considered. Place the live load over the left span only in order to get the worst case positive moment in the 16 ft span. Then place the live load over the right span only in order to get the worst case negative moment in the 8 ft span. Use the larger of the two M₁ values to finalize beam dimensions (b, h, d, which are the same for both spans). Now design the tension steel for each of the two sections separately (using that span's own Mụ). Concrete weight 150lb/ft³, fy = 60,000 psi, and f'e = 4000 psi. A starting steel ratio is provided below. Show sketches of the cross sections, including bar sizes, arrangement, depth and spacing.
