STRUCTURAL DEFORMATION MEASUREMENT OF A MODEL BOX GIRDER BRIDGE

A model of a multiple box girder bridge, constructed at a scale of 1:12, was subjected to an ultimate load test. Deformations were measured photogrammetrically using the method of false parallax. Modifications to the method are described which were necessary to accommodate the three dimensional object and to allow for the fact that the camera stations were not constant from one load stage photograph to the next. An accuracy of plus or minus 0.2 mm in the measured deformations was achieved.(a) /TRRL/
