Assessing Residual Strength of Post-Tensioned Elements with Corrosion-Induced Tendon Failure
The research team will assess the residual strength of post-tensioned (PT) bridge elements with corrosion-induced tendon failures to support the Texas Department of Transportation's (TxDOT) maintenance and evaluation efforts. The research team will develop recommendations for assessing structural capacity and identifying effective maintenance strategies. Experimental testing will be conducted in two phases to evaluate corrosion-induced bond degradation and tendon corrosion effects near the anchor points. These tests will evaluate bond degradation, stress redistribution, and failure mechanisms for strand configurations that are either centrally aligned or offset to one side of the tendon. The research team will also perform an analytical study using finite element modelling to simulate corrosion scenarios and validate structural performance. The research team will develop practical guidelines for Receiving Agency engineers, including assessment methodologies and maintenance recommendations.
