External Post-Tensioning Anchorage, Summary
The integrity of many concrete bridge components depends on post-tensioning (PT). This technology extends the material properties of concrete and gives engineers additional flexibility in bridge design. However, PT depends on the properties of steel, which can corrode, especially in bridge designs, which places PT parts in watery and, often, salty environments. This hazard was highlighted in 2000, when a routine inspection of the Mid-Bay Bridge over Choctawhatchee Bay in Okaloosa County revealed that the polyethylene duct of one of the bridges tendons had cracked.
