Question

Design of Rectangular Beams with Tension Reinforcement Design a rectangular beam section (i.e., select b, h, and the required tension reinforcement) at midspan for a 22 ft-span simply supported beam that supports its own self-weight, a superimposed uniform dead load of 1.25 kip/ft, and a uniform live load of 2 kip/ft. The material properties are f 0 c = 4, 500 psi and fy = 60, 000 psi. Consider a clear cover of 1.5 inches to the #4 stirrups. Follow the procedure described in Example 1 of the class lecture notes; i.e., you start with an assumed reinforcement ratio and then determine tentative values for b and d. For the initial guess, you may estimate a self weight of 0.40 kip/ft (approximately 12% of 1.25+2 kip/ft)

Answer 1

The beam is designed using the reinforcement factor to fine dimensions of the beam and tensile reinforcement in the beam.
