An authorized reprint from Concrete International magazine, published by the American Concrete Institute. This article illustrates the redundancy and reserve capacity of buildings constructed with unbonded tendons. Case studies of laboratory tests and construction incidents or accidents that have demonstrated the capability of unbonded tendons to resist abnormal or catastrophic loadings are presented. Also presented are design recommendations for the enhancement of inherent structural integrity of buildings constructed with unbonded tendons.
