EN The paper presents the problem of damage detection in truss girders. Structural response signal decomposition is performed according to the Mallat pyramid algorithm. Static displacements at the selected point of the structure play the role of measured variables. The geometry and the placement of any defective part of the structure may have a random character. The incorporation of the mathematical stochastic apparatus into the classical (deterministic) analysis of the statics of the structure makes it possible to estimate the reliability measures of the analyzed truss.
