Extracted text: Design rectangular sections for the beam below. fy = 60000 psi and f = 4000 psi. Question 1. Show sketches of beam cross sections including bar sizes, arrangement, and spacing. Span length l = 30 ft. Wp = 2 k/ft (not including beam weight) and w = 2 k/ft. p= 0.18f2/fy. Assume concrete weighs 150 lb/ft3. Use h = d + 2.5 in. Use an initial assumpt of the beam weight as 550 lb/ft. Use the following b/d ratio: 1.8 < b/d="">< 1.9.="" %3d="" wp="" and="">
