Structural Integrity and Damage Evaluation Routine (SIDER) for Quality Control and Health Monitoring of Structures

Abstract

This report presents a broadband vibration-based Structural Integrity and Damage Evaluation Routine (SIDER) which has been shown to be sensitive and repeatable when used on civil infrastructure such as road bridges. The routine looks for features in complex curvature operating shapes, and was developed to assist in the inspection of deep-section FRP structures that cannot be inspected using more conventional methods. The report presents a theoretical outline of the procedure and an experimental demonstration using impacted foam core composite panels. The report also presents the results of a three-year effort inspecting an all-FRP road bridge in Glasgow, Delaware. It is shown that the routine can locate small amounts of incipient damage and can monitor the propagation of this damage.
