A four-span continuous beam of constant rectangular cross section is sup- ported at A, B, C, D, and E. The factored moments resulting from analysis are as follows: At Supports, ft-kips At Midspan, ft-kips Mab 158 м, — 138 м, 3 220 M. = 200 м, — 220 М, 3 138 Mp = 138 %3D be Med 138 %3D = 158 Mae Determine the required final concrete dimensions for this beam, using d = 1.75b, and determine the reinforcement requirements at each critical moment section. Your final reinforcement ratio should not exceed = 0.6po.005. Use f, = 60,000 psi and f.' = 6000 psi.
