The strength evaluation of the gate arm against frictional moment at trunnion bearing is one of the most important part in the safety assessment of the radial gate. In this study, we examined the ultimate strength of the gate arm against the moment using the three gate models which had the different trunnion stiffener length each other. The result showed that the ultimate strength increased with the elongation of the stiffener, and the bending moment distribution along the gate arm went apart from the design distribution with the elongation.
