English abstract:
The paper proposes use of measured structural response to temperature loads for
purposes of damage identification. As opposed to the most common approaches, which
rely on suppressing temperature effects in damage detection, the method proposed
herein utilises measured changes of structural sensitivity to temperature loads.
Applicability of this approach varies by structural type and therefore results of system
identification are presented for different structural types. The method aims at
identifying structural damages that produce stiffness change as well as deformation
states and boundary condition stiffness. In particular, the method is applicable for
evaluations without available measurements known as healthy baseline. Presented
examples comprise 2 bridge monitoring applications.
