Star-shaped truss stiffening double-steel-plate combined shear structure of fabricated steel structure building

Abstract

The invention relates to the field of construction of fabricated buildings, in particular to a star-shaped truss stiffening double-steel-plate combined shear structure of a fabricated steel structure building. The shear structure comprises shear wall peripheral components and is characterized by further comprising outer side double steel plates, diagonal main stiffening trusses, cross-shaped stiffening trusses, studs and internally-poured concrete. The shear structure is simple in structure and reasonable in stress, the steel components are machined in factories, only concrete materials need to be poured on the inner sides of the steel plates on a construction site, on-site formwork erecting is avoided, and the installation efficiency is improved. The shear structure has high in-plane and out-plane rigidity, the mechanical property of materials can be fully exerted, the energy dissipation performance is good, the rigidity and stability requirements in the transportation and hoisting process are met, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the construction field of prefabricated buildings, in particular to a rice-shaped truss-stiffened double-steel combined shear structure of a prefabricated steel structure building. Background technique [0002] Compared with reinforced concrete shear walls, double steel plate-concrete composite shear walls have the advantages of high rigidity, high bearing capacity and strong energy dissipation capacity, and composite shear walls still have good ductility and energy dissipation under large interstory displacements. capacity, and can be matched with steel columns or composite columns with good energy dissipation capacity; the thickness of the composite shear wall is obviously smaller than that of the reinforced concrete shear wall, which can effectively reduce the structure's own weight, reduce the burden of the foundation, increase the usable area of ​​the building, and improve Economical and easy to repair after an earthquake....

AI Technical Summary

Problems solved by technology

[0003] Although the performance and strength of the existing steel plate shear wall can meet the requirements of use, when the outer steel plate is thinner, the out-of-plane rigidity of the steel plate is poor. Out-of-plane buckling will also alternate accordingly, and the stiffness of the bearing capacity will drop sharply during the alternation process, resulting in the pinching phenomenon of its hysteretic curve; During the transportation and on-site hoisting of components, the deformation and stability are very poor, and a large number of temporary reinforcement components need to be added, which greatly reduces the efficiency of transportation and installation
