Abstract

This report details the continuous monitoring of the Kishwaukee Bridge. The data collected includes measurements such as bridge deck acceleration, temperature changes, and crack opening displacement data from local deformation gages. The monitored data also includes modal frequencies, shear strain at known crack locations, and daily truck traffic. The instrument response provides needed information for real-time inspection and planned maintenance and rehabilitation. The main objective of this research was to continue monitoring of the bridge through the retrofitting contract and beyond to validate that the design and retrofitting strategy performed on the bridge arrested the crack growth. The measurements collected from this study will be used to infer possible structural changes and to guide retrofit strategies for compromised components, ensuring the bridge’s integrity and stability into the future. 17.
