Abstract:
The redundancy and reserve capacity of buildings constructed with unbonded tendons is illustrated. Case studies are presented of laboratory tests and construction incidents or accidents that have demonstrated the capability of unbonded tendons and structures containing unbonded tendons to resist abnormal or catastrophic loadings. Design recommendations are presented for enhancing the inherent structural integrity of buildings constructed with unbonded tendons.
