A rectangular pretensioned concrete beam is to be designed to carry superimposed dead and live loads of 300 plf and 1,000 plf, respectively, on a 40-ft simple span. Straight tendons will be used. Time-dependent losses will be approximately 16 percent of the initial stress in the steel. Determine the concrete dimensions (use h=2.5b) and required prestress force and eccentricity, based on ACI limit stresses. Concrete strength f. = 5,000 psi and fái = 4,000 psi. ci
