Problem 2: Design of T-beam Select the reinforcing for T beam AB for the floor system shown. Assume simple supports at A and B. The live load is to be 90 psf, while the dead load in addition to the concrete's weight is to be 120 psf. Concrete is assumed to weigh 150 lb/ft3 . The slab is 4 in. thick, while d is 24 in. and bw is 15 in. fy = 60,000 psi and f'c = 4000 psi. edge L beam Theams 35 ft B 601 Rofte -4012 = 8 *** (a) Calculate the maximum factored moment (note: remember to include the self-weight of slab and beams) (b) Determine the effective flange width (c) Check if a chi (d) Determine the minimum steel area required using trial-and-error approach. Assume moment arm for initial trial equal to 0.9d. Limit the selection of reinforcing steel to #10 bar only and determine the number of bars required to carry the factored moment. (e) Check strain in tensile steel (€:) and determine reduction factor (0). (f) Select minimum bar size to be used as stirrup. Provide minimum side cover if the concrete is not exposed to weather or ground contact and check the spacing of the #10 bars. Check the bottom cover of the beam against minimum cover requirement. (g) Calculate the actual design moment capacity, ØM, and verify that it is greater than M.- (h) Sketch and label your final design.
