Bidirectional energy dissipating soft steel energy dissipater

Abstract

The invention discloses a bidirectional energy dissipating soft steel energy dissipater. The bidirectional energy dissipating soft steel energy dissipater comprises a core energy dissipating component which comprises three rectangular energy dissipating steel plates forming an I-shaped structure, the three rectangular energy dissipating steel plates are respectively a left side rectangular energy dissipating steel plate, a middle rectangular energy dissipating steel plate and a right side rectangular energy dissipating steel plate, and the middle rectangular energy dissipating steel plate is fixed between the left side rectangular energy dissipating steel plate and the right side rectangular energy dissipating steel plate. The dimension parameters of the three rectangular energy dissipating steel plates are specifically defined according to engineering needs and damping requirements. The bidirectional energy dissipating soft steel energy dissipater is combined design of two principles of bend yielding and shear yielding, simultaneously achieves in-plane shear yielding energy dissipating and out-plane bend yielding energy dissipating. A hard core adopts steel with a low yield point, the three rectangular energy dissipating steel plates are reasonably arranged to guarantee the yielding energy dissipating under set inter-story displacement deformation when an earthquake acts, structural damage is avoided, and a protection function is played.

Description

technical field [0001] The invention relates to an engineering structure damping device, in particular to a two-way energy-consuming mild steel energy dissipator, which belongs to the engineering structure energy dissipation damping and vibration control technology. Background technique [0002] The energy dissipation and shock absorption technology of engineering structures is to install energy dissipation devices in certain parts of the structure, and to dissipate or absorb the energy input into the structure through the hysteretic deformation of the energy dissipation devices, so as to reduce the seismic response of the main structure, thereby avoiding The structure is damaged or collapsed to achieve the purpose of shock absorption control. The current energy dissipators are basically made of a single principle of energy consumption, and there are certain deficiencies, such as the unstable bearing capacity curve and the "obvious pinch phenomenon" of the hysteresis curve, ...

AI Technical Summary

Problems solved by technology

The current energy dissipators are basically made of a single principle of energy consumption, and there are certain deficiencies, such as the unstable bearing capacity curve and the "obvious pinch phenomenon" of the hysteresis curve, etc. (such as Figure 4 , Figure 5 and Image 6 shown); the existing mild steel energy dissipators can be divided into: axial yield type, bending yield type, shear yield type and torsional yield type in terms of stress forms. Since the direction of earthquake action is uncertain, therefore It is difficult to ensure that these mild steel energy dissipators with a single energy dissipation direction can effectively play a role in earthquakes
