This includes the full working loads (live loads, superimposed dead loads). By this time, the prestress has reduced due to losses ($P_e$).

Key design concepts (intuitive)
The initial tension put into the steel tendons is not permanent. It reduces over time due to several factors that Rajagopalan explains in detail: Elastic shortening of concrete. Creep and shrinkage of concrete. Relaxation of stress in steel. Friction and anchorage slip (in post-tensioning). Design for Flexure and Shear This includes the full working loads (live loads,
