Abstract

A kind of Novel U-shaped steel plate energy consuming mechanism, comprise the U-shaped steel plate dissipative cell (1) of core and upper junction plate (2) and lower connecting plate (3) and V-type and support (4), it is characterized in that: described dissipative cell (1) realizes power consumption by continuous bend distortion; Upper surface and the upper junction plate of described U-shaped steel plate are connected, and soffit and lower connecting plate are connected; Upper junction plate is parallel with lower connecting plate, and to bear shearing direction consistent for roll direction and the building structure of described U-shaped steel plate dissipative cell (1); When earthquake causes floor gap that larger relative displacement occurs, upper floor drives V-type to support generation translation, because V-type support stiffness is larger, V-type supporting drive upper junction plate generation translation, therefore upper junction plate and lower connecting plate generation relative horizontal displacement, upper lower connecting plate drives U-shaped steel upper and lower sides generation relative displacement, drives U-shaped steel to be out of shape thus, thus produce power consumption benefit, be a kind of energy-dissipating type damper.

Description

A kind of Novel U-shaped steel plate energy consuming mechanism
Technical field
The present invention relates to a kind of power consumption damping mechanism, belong to engineering structures damping and technical field of isolation, be mainly used in the power consumption antidetonation of building.
Background technology
For making building structure have stronger opposing earthquake or the ability of wind load, usually need the anti-seismic performance strengthening structure itself, to resist the impact that earthquake motion brings; Along with the further understanding to earthquake motion, the application of damping mechanism in earthquake resistant structure is more and more extensive.Friction energy-dissipating damper, viscoplasticity energy-consumption damper and metal damper etc. that structure is commonly used at present, achieve good effect in structural seismic.Utilize hardware consumed energy principle in large deformation situation, metal energy-dissipation damper effectively can consume the energy of geological process.
Current metal energy consuming mechanism, usually can be excessive owing to being out of shape, and loses energy-dissipating property, can only single use; And due to the restriction of size, energy-dissipating property is limited.Novel U-shaped steel plate energy consuming mechanism utilizes structure relative floor displacement to reach power consumption effect, can apply, and can resist repeatedly geological process, effective earthquake energy in structure different parts.
Summary of the invention
Content of the present invention is to provide a kind of U-shaped steel plate power consumption damping mechanism, and technical scheme of the present invention is as follows:
A kind of power consumption damping mechanism, comprise dissipative cell, upper junction plate and lower connecting plate, V-type supports, described dissipative cell is U-shaped steel, and upper junction plate and lower connecting plate and V-type are supported for stiffener; Wherein, the two sides of U-shaped steel is separately fixed at upper junction plate and lower connecting plate, and one end that V-type supports is connected with top bean column node, and the other end is connected with upper junction plate.
Described damper is U-shaped steel plate.Its size is less, and concrete size is calculated by energy-dissipating property to be determined.
When earthquake causes floor gap that larger relative displacement occurs, upper floor drives V-type to support generation translation, because V-type support stiffness is larger, V-type supporting drive upper junction plate generation translation, therefore upper junction plate and lower connecting plate generation relative horizontal displacement, upper lower connecting plate drives U-shaped steel upper and lower sides generation relative displacement, drives U-shaped steel to be out of shape thus, thus produces power consumption benefit.
Beneficial effect:
Adopt U-shaped steel plate damping mechanism of the present invention, structure diverse location can be arranged in, convenient, flexible; Can realize larger deflection, with earthquake energy, structure is simple, is convenient to implement; And by different U-shaped steel types, realize the needs of different building structure, effectively improve the anti-seismic performance of building; Because U-shaped steel deformation performance is good, energy-dissipating property is good, can repeatedly use, have broad application prospects in earthquake.

Detailed description of the invention
As shown in Figure 1, U-shaped steel plate damping mechanism embodiment of the present invention is as follows:
As shown in Figure 1, the U-shaped steel plate damping mechanism of one of the present invention, comprises the U-shaped steel plate dissipative cell (1) of core and upper junction plate (2) and lower connecting plate (3) and V-type and supports (4); Wherein, the two sides of U-shaped steel plate (1) is separately fixed at upper junction plate (2) and lower connecting plate (3), one end that V-type supports (4) is connected with top bean column node, and the other end is connected with upper junction plate (2).Wherein, U-shaped steel plate (1) adopts dissipative cell.It specifically comprises following two embodiments:
Embodiment 1:
As shown in Figure 2, between deck, when earthquake causes floor gap that larger relative displacement occurs, upper floor drives V-type to support generation translation, because V-type support stiffness is comparatively large, and V-type supporting drive upper junction plate generation translation, therefore upper junction plate and lower connecting plate generation relative horizontal displacement, upper lower connecting plate drives U-shaped steel upper and lower sides generation relative displacement, drives U-shaped steel to be out of shape thus, thus produces power consumption effect.
Embodiment 2:
As shown in Figure 3, at base isolation layer, due to geological process, there is relative horizontal displacement in neoprene bearing up and down, and superstructure drives V-type to support generation translation, because V-type support stiffness is larger, V-type supporting drive upper junction plate generation translation, therefore upper junction plate and lower connecting plate generation relative horizontal displacement, upper lower connecting plate drives U-shaped steel upper and lower sides generation relative displacement, drive U-shaped steel to be out of shape thus, thus produce power consumption effect.
Below be only a specific embodiment of the present invention, enforcement of the present invention is not limited thereto.
