Q.1 Determine the short and long term camber of SST36 having a span of 75 feet with only self weight acting. Assuming concstant eccentress of pre-stressing reinforcement. The self-weight of beam can be taken at 594 lbs/ft.Assue creep co-efficient equal to 2.5 and free shrinkage sstrein of -0.40x10-³ in/in. Initial jacking stress may be 0.75 FPU Fc' may be taken as 5000 psi and that at transfer at 3500 psi. The beam has 14, ½" low relaxation strands.what can be the deflection if superimposed DL is 60 psf?
