Frame joint of rectangular concrete-filled steel tube column employing knee-bracing stiffened steel plates
The invention discloses a frame joint of a rectangular concrete-filled steel tube column employing knee-bracing stiffened steel plates. The frame joint comprises thin-walled rectangular steel tubes, cast-in-place concrete, I-steel beams and a knee-bracing steel plate stiffening rib.The knee-bracing stiffened steel plates are arranged in a joint core region and a plastic-hinge region for an end portion of a column steel tube. The stiffened steel plates and the inner wall of a steel tube are welded to three dividing points of a steel tube wall at 45-degree angles. The stiffened rectangular steel tubes and the I-steel beams are welded and are used for pouring concrete in order to form the frame joint of the rectangular concrete-filled steel tube column employing the knee-bracing stiffened steel plates.The frame joint of the rectangular concrete-filled steel tube column employing the knee-bracing stiffened steel plates has following beneficial effects: a novel joint form can effectively help delay local buckling of the steel tube, thereby improving constraint effect of concrete; tension of steel beam flanges can be effectively transferred by the knee-bracing steel plate stiffening rib and bending moment of the steel beams can be further effectively transferred such that the joint can satisfy the need of aseismic design; and the frame joint of the rectangular concrete-filled steel tube column employing the knee-bracing stiffened steel plates is novel framework node form featuring a fine mechanical property, convenient construction and economic feasibility.
