The structural damage identification analyses of braced frames were performed by filtering algorithms as a frame work of inverse problem. In this study, three kinds of filtering algorithm based on the Wiener filter, the projection filter and the parametric projection filter were employed to detect the structural damage of a five-story braced frame models defined by the reduction of lateral stiffness of the braces. Natural frequencies corresponding to each eigen-mode measured by the experimental modal analysis are effectively used as the observation data characterized by the change of structural stiffness. The notable characteristics of each filtering algorithm in applying the structural damage identification analysis are made clear through several numerical calculations.
