Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] According to the introduction of the present invention, a small energy dissipator such as Figures 1 to 6 As shown, it includes a top plate 5 and a bottom plate 6 that are parallel to each other, and an energy-consuming steel sheet is arranged in the middle of the top plate 5 and the bottom plate 6, and the energy-consuming steel sheet connects the top plate 5 and the bottom plate 6; One first-stage energy-consuming steel sheet 1 and two second-stage energy-consuming steel sheets 2 are set, and the two second-stage energy-consuming steel sheets 2 are set at the two sides of the first-stage energy-consuming steel sheet 1 as the center line. The dimensions of the first-stage energy-consuming steel sheet 1 are 400mm in height, 375.4mm in width, and 24mm in thickness, and the dimensions of the second-stage energy-consuming steel sheet 2 are 400mm in height, 263.4mm ...

Abstract

The invention discloses a staging energy dissipater. The staging energy dissipater comprises a top plate and a bottom plate which face to face in parallel, wherein energy dissipation steel sheets are arranged between the top plate and the bottom plate and connected with the top plate and the bottom plate. The energy dissipation steel sheets comprise one first-stage energy dissipation steel sheet and two second-stage energy dissipation steel sheets parallel with each other, the two second-stage energy dissipation steel sheets are arranged at the two sides of the first-stage energy dissipation steel sheet with the first-stage energy dissipation steel sheet as the middle line, the yield point of the materials of the first-stage energy dissipation steel sheet is higher than the yield point of the materials of the second-stage energy dissipation steel sheets, a parabola type hole is formed in each energy dissipation steel sheet and is formed by a sets of parabolas whose openings are the same in size and are opposite in pairs, the symmetry axis of the parabolas is parallel with the top plate and is located in the middle of the corresponding energy dissipation steel sheet, and the parabola type hole in the first-stage energy dissipation steel sheet is lager than the parabola type holes in the second-stage energy dissipation steel sheets. The staging energy dissipater has the advantages of being easy to design and manufacture, convenient to install and replace, stable in hysteretic behavior, low in manufacturing cost and capable of dissipating energy in a staging mode.

Description

technical field [0001] The invention relates to the field of vibration prevention in construction engineering, in particular to a vibration damping device for suppressing the structural vibration response of engineering structures under the action of earthquake and wind vibration. Background technique [0002] Low yield point steel has a lower yield point, which is beneficial for the energy dissipator to enter the yield energy dissipation before the structural member, and has good plasticity, ductility and hysteretic properties, so it has a good and stable energy dissipation capacity. Due to the above advantages, low-yield point steel is particularly suitable as steel for seismic use, and has gradually been recognized and valued by the industry, and has now become a new steel grade and key steel grade for seismic use. With the gradual rise of low-yield point steel materials and the development and application of passive control theory at the end of the 20th century, low-yiel...
