A comparative study on the effectiveness of system parameters in monitoring pre-load loss in bolted joints

This article presents the monitoring of bolt loosening in a single bolted lap joint between two steel beams. The bolt loosening is initially studied using system modal parameters for various boundary conditions. Natural frequency and modal damping ratio in lower modes were not found to be reliable....
