In recent years, the fatigue durability of steel plate concrete composite decks has been evaluated by the wheel trucking test in Japan. The composite decks are applied to continuous steel twin-girder bridges and U-shaped steel girder bridges. Slabs are played important roles as a structural element. In order to study the behaviors of the continuous composite girder with the composite deck, a static loading test for the mid-supporting point area specimen was conducted. Furthermore, threedimensional finite element analyses for the specimens were carried out to compare with the measured values of the static loading test, and to evaluate stress distribution of concrete and longitudinal re-bars.
