According to the Japanese Specifications for Highway Bridges, in high strength bolted frictional joints, verifications of the resistances in after-slip behavior are required. In bearing type joints, a filler plate is extended beyond splice plates to connect the filler to a member by additional bolts (tight type filler), but there're few examples of high strength bolted frictional joints with it. In this study, effects by tight type filler in serviceability limit state and ultimate limit state of high strength bolted frictional joints are quantitatively examined by FEM analysis. As a result, tight type filler is effective in slip strength and shear strength of bolts, but there's a risk to deterioration of yield strength and breaking strength of connected plate.
