As part of the investigation of the dynamic instability of the gate closely related to the Folsom dam Tainter-gate failure, and in order to assure the dynamic stability of the gate, the field vibration tests on three full-scale operational Tainter-gates were conducted. From these tests, the possible existence of another coupled-mode self-excited vibration mechanism, which involves the dangerous dynamic coupling of the whole gate rigid-body rotational vibration with a "parallel" bending of the skinplate was suggested. This paper presents that the 2-dimensional model test results, which was undertaken to confirm the existence of the coupled-mode self-excited vibration with skinplate parallel bending mode.
