Comments on Structural Condition Analysis Based on Strain Measurements on Tripod Model

Abstract : Selected strain measurements performed on tripod model are described in this paper. Two problems are investigated here. First, the influence of bonding procedure and surface's curvature on initial strain in optical sensor is shown. It seems that initial strains due to bonding procedure and curvature can be respectively high in comparison with allowed strain range of the optical sensors. Second, the ability of strain sensors to indicate changes in boundary condition in one leg of the tripod is also shown. For tripod model changes in boundary conditions can be detected by sensors not necessarily located at the bottom part of the structure. Maximal shear strain can be valuable indicator of such changes.
