The precast slab with the void part for stud arrangement is sometimes used in exchanging the RC slab due to shortening of a construction period and arrangement of shear connectors. Then, it is required to investigate the composite action between the steel girder and the precast slab with the grouped studs in detail, and the effect of installing the precast slab partially. In this study, we conducted the composite girder test having the precast slab with the grouped studs and the one having the RC slab with the normal stud arrangement. As a result, the static behavior are compared between both composite girders and the corresponding push-out specimens, and the composite action of the girder with the precast slab is clarified in detail.
