Problems solved by technology

[0002] As an energy-dissipating component, the mild steel energy-dissipating wall utilizes the characteristics of low yield strength and strong plastic deformation ability of mild steel, and has the advantages of simple structure, low cost, and convenient replacement. Small, when bearing the horizontal shear force between the structural layers, the out-of-plane buckling of the steel plate is prone to occur, resulting in obvious pinching of the hysteretic curve and affecting the overall energy dissipation capacity

Abstract

The invention discloses a buckling restrained soft steel energy dissipation wall which comprises a first steel plate wall (111), a second steel plate wall (112) parallel to the first steel plate wall (111), precast concrete walls (2), split bolts (6), steel jacket plates (8) and polyfluortetraethylene plates (9), and is characterized in that the first steel plate wall (111) and the second steel plate wall (112) adopt soft steel; the precast concrete walls (2) are arranged between and on the outer sides of the first steel plate wall (111) and the second steel plate wall (112); and the polyfluortetraethylene plates (9) are additionally backed between steel plate walls (1) and the precast concrete walls (2). The wall is simple in structure and convenient to construct, and has good hysteresis and energy dissipation capabilities. The novel buckling restrained soft steel energy dissipation wall has a wide engineering application prospect.

Description

technical field [0001] The invention relates to a novel anti-buckling soft steel energy-dissipating wall, which is suitable for various structural systems in earthquake-prone areas, so as to effectively control the interstory displacement of the structure and reduce the seismic response of the main structure. Background technique [0002] As an energy-dissipating component, the mild steel energy-dissipating wall utilizes the characteristics of low yield strength and strong plastic deformation ability of mild steel, and has the advantages of simple structure, low cost, and convenient replacement. Small, when bearing the horizontal shear force between the structural layers, the out-of-plane buckling of the steel plate is prone to occur, resulting in obvious pinching of the hysteretic curve and affecting the overall energy dissipation capacity. [0003] Aiming at the above problems, the present invention proposes a new type of anti-buckling soft steel energy-dissipating wall. T...
