Abstract. The statistical moment-based damage detection method with approximate parametric solutions of the stationary second-order moments of the response is proposed for damage detection of a bridge. The method is based on an approximate explicit solution recently proposed by the authors, which allows to explicitly relate second-order moments of the nodal displacements and velocity to the structural stiffness. Application on a bridge is reported to check the consistency of the method and to investigate the influence of the entity of the damage and of the application point of the force on the identification procedure.
