Abstract
By adoption of the grouped arrangement of stud shear connectors in steel-concrete composite constructions, the prestressing force by tendons is able to introduce only in concrete member easily and effectively. As one of its example, an application of the grouped studs to the continuous composite girder was studied in this paper. In addition to the push-out test in static and fatigue of the grouped studs, the static and fatigue loading test of prestressed concrete slab by using the full-sized specimen was also carried out. The applicability of grouped studs to the continuous composite girder was confirmed by calculation example based on the test results and the design rules.
