IMPROVED SEMI-CONCRETE FILLED TUBE COLUMN IN WHICH A STEEL PLATE RESISTS A SHEAR FORCE AND IN WHICH A REINFORCING BAR, A COLUMN BEAM, AND CONCRETE RESIST AN AXIAL FORCE AND MOMENT

摘要

PURPOSE: An improved semi-concrete filled tube column is provided to obtain economic effects by reducing the thickness of a steel plate and a welding amount.;CONSTITUTION: An improved semi-concrete filled tube column (100) includes a polygonal steel plate (110), a plurality of reinforcing bars (120), concrete, column steel frame, and a beam bracket (150). The steel plate includes a hollow in a tube shape and performs a role of a mold. The steel plate resists a shear force after the column is constructed. A plurality of the reinforcing bars is arranged at the corner of the hollow on the steel plate, and the concrete is placed in the hollow of the steel plate. The reinforcing bars and concrete resist an axial force and moment. The column steel frame is installed in the center of the hollow of the steel plate, and the beam bracket is installed on the upper end of the steel plate.;COPYRIGHT KIPO 2013
