    The expansion joints are expected to have movement capacity, bearing capacity for static and dynamic loading, water-tightness, low noise emission and traffic safety. In particular, the failure due to impact loading is the main cause for the observed damages. The problem of dynamic behavior of the expansion joints is so complex that the impact factor for vehicle load that is governed by traffic impact plays a key role. In order to overcome this difficulty, the cantilever-toothed aluminum joint (finger joint) is considered to be one of the promising joints under impact loading. In this study, from the viewpoint of design methodology, numerical studies for impact behavior were conducted for aluminum alloy expansion joints with perforated dowels. The design impact factor for the expansion joints with the perforated dowels against traffic impact loading was examined by using numerical simulations.
