Performance of Earthquake-Damaged Reinforced Concrete Bridges with Repaired Columns - Phase II

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.

The technology transfer will be via the publications. The PI and her research group will also present this work to the research community in at least one technical presentation at a national conference.

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.
