Potential Benefits
An appropriate balance (combination) of retrofit and repair can result in a bridge that is serviceable shortly after an earthquake occurs while reducing initial costs and uncertainties.
Brief Description of Research Project
This is Phase II of a project that will evaluate the seismic performance of bridges with columns that have been repaired due to previous earthquake damage. This phase of the project seeks to develop a framework to optimize the levels of (pre-earthquake) retrofit and (post-earthquake) rapid repair needed to maintain the serviceability of a bridge after an earthquake occurs. Numerical simulation will be used to determine how different methods and levels of retrofit and repair of the column member effect the system-level response of the bridge structure.
