Inspection of Unbonded Post-Tensioning Tendons for Building Structures
Post-tensioned concrete building structures are common in today's marketplace. Properly designed and constructed, they are very durable, allow for creative architectural designs by providing more open space with fewer columns, and can be quite economical. Current building code requirements mandate unbonded tendons to be fully encapsulated to provide improved corrosion resistance. While encapsulated tendons have more components and are a bit more complex to install than nonencapsulated tendons, the end result is a more durable structure. The authors hope that this discussion shows that inspection of the installation of unbonded PT tendons and related components is an essential part of the construction process. It's clear that inspection minimizes construction problems and helps provide a more durable structure with lower life-cycle costs. But project site inspection is not just the responsibility of a third-party inspector hired by the owner -- it is also the duty of the contractor and the related subcontractors. The cited ACI and PTI publications are valuable reference documents.
