A pretensioned prestressed beam has a rectangular cross section of 6 in. width and 20 in. total depth. It is built using normal-density concrete with a specified strength f! are as follows: f; = 165 psi, fe = -1800 psi, f, = = -1800 psi. The effectiveness ratio R may be assumed equal to 0.80. For these conditions, find the initial prestress force P; and eccentricity e to maximize the superim- posed load moment Ma + M, that can be carried without exceeding the stress limits. What uniformly distributed load can be carried on a 30 ft simple span? What tendon profile would vou recommend? = 4000 psi and a strength at transfer of f = 3000 psi. Stress limits 475 psi, and fes
