New failure model of finger-type bridge joint due to its asymmetric vibration

Recently, the failure of finger-joints can often be observed. Most of the failure is due to the failure of the anchor bolts rather than of the plate itself. Here, a new asymmetric vibration failure model is proposed. The numerical results are shown that the asymmetric vibration of finger-joints is more important for the failure of anchor bolts which fasten a finger-joint to the deck than the traditional static mode.
