ABSTRACT
The virtual forces of the original local flexibility method are restricted to inducing stress on the local parts of a structure. To circumvent this restriction, we developed pseudo local flexibility (PLFM) method that can successfully detect damage to hyperstatic beam structures using fewer modes. In this study, the feasibility to detect damage of a truss bridge using PLFM using a numerical bridge model is discussed. A numerical model of a real truss bridge is constructed with 5 different damage cases. This preliminary case study is the first step to employ PLFM to a real bridge. A promising results of damage localization using the first three modes of the bridge are obtained in this study.
