Abstract: A nondestructive crack detection (NCD) scheme to locate a crack and estimate the crack size by using changes in the modal parameters of a class of bridges is presented in this paper. First, the theory underlying a ...

Abstract: The impact of model uncertainty on the damage-prediction accuracy of a nondestructive damage-detection technique when applied to a model plate girder is assessed. First, a damage-detection algorithm to locate and size ...

Abstract: In this study, the effect of temperature variation on prestress force monitoring by fiber Bragg grating (FBG) sensors embedded in prestressing tendons of prestressed concrete (PSC) girders is estimated. First, a fiber optic ...

Abstract: An algorithm of topological ordering of vertices is proposed for generating a unique edge list of a given graph, and used for the isomorphism test. This also makes it possible to find the ...
