STEEL BOX GIRDER COMPOUNDED WITH CONCRETE SLAB BY SHEAR CONNECTORS

摘要

PURPOSE: A shear connector attached steel box girder structure compounded with a concrete slab by a shear connector is provided to be effective and to have economical effect by reducing the installation amount of longitudinal and horizontal ribs. CONSTITUTION: In a shear connector attached steel box girder structure compounded with a concrete slab by a shear connector, many spot spacers are attached to a longitudinal reinforcement rib attachment line in the longitudinal direction instead of reinforcement ribs attached to the top of a lower flange supported to a support in the longitudinal and horizontal directions, many spot spacers are installed to a horizontal reinforcement rib attachment line in a row and buried under concrete, and a shear connector is installed to the top of an upper flange of a double composite steel box girder.
