Long span bridge and slender element of the bridge is sensible to dynamic wind action such as flutter buffeting, vortex induced vibration and galloping. For arch bridge, vibration of hanger due to dynamic action of the bridge has been experienced including hanger vibration of Tayan Bridge. The possible phenomena of the vibration are flutter, galloping and vortex induced vibration. This paper presenting the study of galloping phenomenal on the hanger of the Tayan Bridge. Several shape of the bridge hanger has been considered in this study. Computation Fluid Dynamic has been used to determine the static wind coefficient of the hanger. Glauert-Hartog Criteria has been applied to examine the performance of the bridge hanger to galloping. The result showed that that only circle shape that is not experiencing galloping
