Multiple arched porous metal damper

Abstract

The invention provides a multiple arched porous metal damper, and relates to a shake controller for a building structure. The multiple arched porous metal damper comprises an energy consumption part, fixation parts, bolt holes, internal circular holes, an I-shaped sway brace and an I-shaped steel beam, wherein the energy consumption part of the damper is arched in outline, the energy consumption part is internally provided with a plurality of circular holes, and the circular holes are regularly arranged according to an arched trend. The fixation parts are rectangular, and are internally provided with the bolt holes, the fixation parts and the energy consumption part are mild and tangent to transit, two or more mild steel dampers are assembled together, the two lower fixation parts are connected with the I-shaped sway brace by virtue of the rectangular steel plate, and the upper fixation part is connected with the I-shaped steel beam. The steel material of the damper is larger in yield surface, good in energy consumption effect and high in steel material use ratio, the whole rigidity of the building structure can be increased when the damper is used under a normal status, in the earthquake, the earthquake reaction of the building structure can be reduced due to the yield energy consumption of the steel plate damper, and the building structure can be well protected.

Description

technical field [0001] The invention relates to a building structure vibration control device, in particular to a building compound arched porous metal damper for building structure vibration control. Background technique [0002] Because metal materials have good hysteresis properties after entering plasticity, they are used to make various types of energy-consuming devices. The metal damper device is generally a passive energy-dissipating shock-absorbing device assembled from low-yield point or extremely low-yield point steel plates and its positioning device. The anti-seismic mechanism is simple, the cost is low, and the effect is remarkable. At the same time, the energy-dissipating device is generally installed in the structure as a non-load-bearing component. Under normal use, it can improve the overall stiffness of the structure; It can meet the requirements of anti-seismic fortification. At this time, the deformation of the structure is relatively small, and the meta...

Problems solved by technology

[0004] However, after some mild steel dampers yield under force, the local stress and strain concentration phenomenon is serious, resulting in uneven plastic distribution of the damper, and the potential of the material is not fully utilized.
