Energy dissipation support-embedded profile steel concrete filled steel tubular column connecting structure

Abstract

The invention discloses an energy dissipation support-embedded profile steel concrete filled steel tubular column connecting structure which comprises a vertical steel tube, concrete poured in the steel tube, vertical profile steel embedded in the concrete, a connecting beam and a supporting connecting plate, the connecting beam is horizontally arranged, one end of the connecting beam is embedded in the concrete and fixedly connected with the profile steel, the other end of the connecting beam penetrates out of the steel pipe through the steel pipe, the supporting connecting plate is partially embedded in the concrete and fixedly connected between the bottom of the connecting beam and the profile steel, and the part, located outside the steel pipe, of the supporting connecting plate is provided with an energy dissipation supporting connecting position. The energy dissipation supports transmit loads to the profile steel through the supporting connecting plates, the steel beams effectively transmit the loads at the beam ends to the embedded profile steel through the connecting beams, the node is clear in force transmission path, the concrete columns cannot be locally damaged, and the node is large in rigidity and high in safety and stability.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to an energy-dissipating support-embedded steel pipe concrete column connection structure. Background technique [0002] Embedded steel-filled concrete-filled steel pipe columns are formed by embedding steel-shaped steel pipes in ordinary steel-filled steel pipe concrete columns and then pouring concrete. Embedded steel-filled concrete-filled steel pipe columns can give full play to the mechanical properties of steel and concrete, and have superior bearing capacity, seismic performance and convenient construction. Embedded steel-filled steel pipes can improve their bending resistance and effectively solve the disadvantages of bending moments on ordinary steel-filled steel pipe concrete columns At the same time, due to the effective restraint of the concrete on the embedded high-strength steel, the high-strength steel is not easy to lose stability, and the material streng...

Problems solved by technology

[0003] Embedded CFST columns are used in heavy-duty industrial workshops and other structures, and usually need to set up energy-dissipating supports and other lateral components. Due to the increase in energy-dissipating supports, the structure of the embedded CFST column-beam-column connection structure is more complicated; The existing connection structure usually connects the energy-dissipating support directly through the concrete and the embedded steel. The force transmission path of the connection structure is not good, and it is easy to cause local damage to the concrete column at the connection structure.
