PHProblem 5
A four-span continuous beam of constant rectangular cross section is supported at A, B, C, D, and E. The
factored moments resulting from analysis are as follows:
Determine the required final concrete dimensions for this beam, using d = 2b, and determine the
reinforcement requirements at each critical section. Your final reinforcement ratio should not exceed 60%
of the maximum steel ratio for tension-controlled sections. Use f’c = 42 MPa and fy = 420 MPa
