Abstract

The invention relates to the field of structural engineering in civil engineering and discloses a concrete filled steel tube composite frame structure system. The concrete filled steel tube composite frame structure system comprises any one beam-column system of a frame structure, a frame-shear wall structure and a suspended structure, which comprises frame columns, frame girders, beam column joints, composite column variable cross-section joints and composite column variable concrete filled steel column joints; column type steel tubes are arranged inside the frame columns and are filled with column core concrete; the column type steel tubes are wrapped by column outer wrapped concrete; the frame girders are filled with girder concrete; the beam column joints are arranged on the connecting regions of the frame columns and the frame girders; the frame columns comprise composite column lower columns; composite column upper columns or concrete filled steel tube upper columns are arranged on the composite column lower columns; the composite column lower columns and the composite column upper columns are connected by the composite column variable cross-section joints; and the composite column lower columns and the concrete filled steel tube upper columns are connected by the composite column variable concrete filled steel column joints. The concrete filled steel tube composite frame structure system has the advantages that the dead load is small; and the anti-seismic property and the fire resistance are good.

Description

technical field [0001] The invention relates to the technical field of structural engineering in civil engineering, in particular to a steel pipe concrete composite frame structure system. Background technique [0002] With the continuous enhancement of my country's economic strength and the rapid development of the construction industry, various large-span and high-rise structures have emerged, which put forward higher requirements for structural forms and construction techniques. At present, the types of long-span and high-rise structures mainly include reinforced concrete structures, steel structures and steel-concrete composite structures. Due to the interaction and cooperative work of steel and concrete, composite structures such as steel-filled steel tube concrete and steel-reinforced concrete have the advantages of high bearing capacity, high bending and torsional rigidity, and good fire resistance, which can meet the growing structural design requirements. Demand, c...
