This paper is concerned with the identification analysis of structural damage detection on five-story braced frame based on free vibration equation and filtering theory. The structural damage to be detected on analyses is assumed in a brace arranged at each story. The structural damage identification problem is formulated as an inverse problem in structural engineering and computational mechanics fields. The problem must be solved under the consideration of stochastic properties on mathematical models. In this study, three kinds of filtering algorithm that is able to consider the stochastic properties, the extended Kalman filter, projection filter and parametric projection filter are employed as the analytical algorithm of the results of inverse problem. Adaptability and characteristics of each algorithm are discussed from the results of inverse analysis.
