ABSTRACT:
A fatigue resistant shear connector for attaching a bridge deck to a top flange of a girder. The shear connector includes a shear resistor attached to the top flange. A portion of the shear resistor extends upward from the top flange into the bridge deck to cause composite cooperation between the bridge deck and the girder. A resilient spacer is juxtapositioned with top flange and at least one friction plate underlies the top flange. An adjustable fastener attaches between the friction plate and the shear resistor to draw the friction plate and the shear resistor together against the top flange to compress the resilient spacer and firmly attach the shear connector to the girder with a desired amount of force to resist fatigue forces without reducing the strength of the girder.
