Abstract

The invention discloses a steel-FRP-environmentally friendly concrete composite column and a construction method thereof. The composite column includes at least one vertical section, and the vertical section includes square steel pipes and round FRP pipes. The round FRP pipe is set in the square steel pipe, the space between the square steel pipe and the round FRP pipe is filled with ordinary concrete, and the round FRP pipe is filled with environment-friendly concrete. According to the steel-FRP-environmentally friendly concrete composite column of the present invention, the advantages of light weight, high strength and good corrosion resistance of the FRP material are utilized, and new sustainable development materials can be used to save costs, and the composite column has high bearing capacity. , high ductility, light weight and so on. At the same time, the set square steel pipe increases the stiffness and ductility of the composite column, improves the anti-seismic and impact resistance, facilitates the connection of nodes, and reduces the difficulty of construction, so that the composite column becomes a low-cost and high-performance component and obtains high technical and economic benefits. It can be used in engineering structures such as super high-rise buildings and long-span bridges.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a steel-FRP-environmentally friendly concrete composite column and a construction method thereof. Background technique [0002] As building heights and bridge spans continue to increase, composite columns have received extensive attention in the engineering field. At present, the main components of frame structures, super high-rise buildings and long-span bridges include reinforced concrete columns, steel pipe concrete columns, and composite steel pipe concrete columns. These composite columns all play their own advantages in the structure, but There is no shortage of room for improvement. [0003] For example, reinforced concrete columns have the disadvantages of long construction period, high difficulty, and low efficiency, and ordinary reinforced concrete columns are also difficult to meet the bearing capacity requirements under high axial compression ratio. For ...
