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.

Keywords
