A rectangular concrete beam measures 12 in. wide and has an effective depth of 18 in. Compression steel consisting of two No. 8 (No. 25) bars is located 2.5 in. from the compression face of the beam. If fc = 4000 psi and fy = 60,000 psi, what is the design moment capacity of the beam, according to the ACI Code, for the following alternative tensile steel areas? (a) As = three No. 10 (No. 32) bars in one layer, (b) As = four No. 10 (No. 32) bars in two layers, (c) As = six No. 9 (No. 29) bars in two layers. (Note: Check for yielding of compression steel in each case.) Plot Mn versus p and comment on your findings. A rectangular concrete beam measures 12 in. wide and has an effective depth of 18 in.
