(Problem 3-5) Design a rectangular section for the beams and loads shown in the following figures. Show sketches of the cross sections, including bar sizes, arrangement, and spacing. Use p = P0.005. Assume concrete weighs 150lb/ft³, fy = 60,000 psi, and f'c = 4000 psi. You will need to estimate and include self- weight in your calculation of M₁. 3. Once you design the section, check if M, <M, PLL 40k WDL =3k/ft 10ft * 10ft
