Numerical Assessment on Bonded and Unbonded Prestressed Concrete Beams

open access: yesBuildings, 2022
The tendon stress in bonded prestressed concrete (BPC) beams is section-dependent while it is member-dependent in unbonded prestressed concrete (UPC) beams, leading to marked difference between these two structural systems.
