The structural damage identification analysis is performed for planar truss as the frame work of inverse analysis. In this study, three kinds of filtering algorithm based on Wiener filter, projection filter and parametric projection filter are employed as the inverse analysis method that is able to consider the stochastic properties. As the observations in these filtering algorithms the natural frequencies are effectively used. In order to verify the characteristics of each filter,three kinds (two types) of truss are selected in performing numerical example. The first type is a symmetric truss whose both ends are simply supported. And other type is a cantilever-type an-symmetric truss. The notable characteristics of each filtering algorithm in applying the inverse problem are made clear through numerical simulations.
