A simply supported beam for a building interior with 18 ft span has a cross section of 12 in width and 21 in overall depth. The beam is made with 5 ksi compressive strength concrete and 60 ksi reinforcing steel. The beam supports a uniform service superimposed dead load of 1.6 kip/ft, and a uniform service live load of 80 psf throughout the span. The beams are laterally spaced 20 ft apart c/c. Design this beam and show in a sketch.
