INFLUENCE OF SAMPLING INTERVAL ON DEFLECTION- INFLUENCE-LINE-BASED DAMAGE DETECTION IN BEAMS
Abstract
In this paper, the influence of sampling interval on reliability of damage detection and damage localization based on comparison of deflection influence lines and their derives (slope and curvature) for intact and damaged state is investigated. The numerical analysis is conducted on a simply supported beam with one damaged section for different sampling interval and different position of sampling points to damaged section.
