Abstract:
Current building codes require unbonded tendons to be fully encapsulated to provide improved corrosion resistance. To minimize construction problems, ensure design compliance, and eliminate or minimize failure mechanisms and tendon placement issues, all unbonded tendons have to be inspected. Tendon handling and placement considerations, concrete blowouts, corrosion-induced failures, and personnel qualifications are covered.
