Numerical analysis of three-span slab post-tensioned with unbonded
tendonsat ultimate.
The design of multi-span structures post-tensioned with unbonded tendons may differ from the assigned one for reinforced structures or structures post-tensioned with bonded tendons. In some cases Ultimate Limit State can be reached by different loading patterns to which we got used to i.e. load cases which result in maximum values of bending moments in spans and at supports. This behaviour is related to the lack of bond between concrete and strands and the assumption that the force in tendons has a uniform value between anchorages.
