Question

Immediately after prestressing, a post-tensioned bonded concrete beam has a prestress of 1560
kN in the steel, which gradually reduces to 1330 kN. In addition to its own weight of 4.40 kN/m,
the beam bears two live loads shown in the figure below. Calculate the mid-span fiber stresses:

a. with full prestress and no live load in the initial condition
b. with full live load and in final condition after all losses had occurred
