Despite many combined research efforts, outstanding needs exist to develop robust safety-estimation methods for large complex structures. This paper presents a practical damage identification scheme which can be applied to truss structures using only limited modal responses. Firstly, a theory of pattern recognition (PR) is described. Secondly, existing damage-detection algorithms are outlined and a newly-derived algorithm for truss structures is proposed Thirdly, PR detectors for damage detection are formulated by integrating the PR theory and the existing demage-detection algorithms for truss structures. Finally, the feasibility of the proposed scheme is evaluated using numerical examples of plane truss structures.
