Project Name Time-dependent Considerations of I-35W St. Anthony

Project Number (if applicable) 99008 WO42

Summarize purpose of the contract, including why it was necessary: Predictive modeling of creep and shrinkage is expected to have implications on long-term bridge maintenance. Specifically, accurate models of time-dependent behavior can inform decisions about the need or timing of restorative measures designed to counteract excessive deflections, balance out large prestress losses, or prevent development of tension in the concrete. The information gained on the usage of the structural monitoring system over long periods of time should prove useful towards the development of future monitoring schemes. As an immediate benefit, a system will be developed to automate the ongoing prediction of static readings, such as linear potentiometer data at the expansion joints and strain gages readings for structural deformation. Ultimately, better understanding of concrete creep and shrinkage witnessed in existing structures should influence the design of similar structures in the future, leading to a more robust infrastructure.
