Abstract
The invention discloses a kind of method improving building or antivibration capability of bridge, building or bridge are installed discoidal metal damping member, this metal damping member has the disc steel plate of more than three, friction solid damping material is filled between each disc steel plate, when being relatively rotated by disc steel plate, the frictional damping produced between disc steel plate and solid damping material reaches the object of the seismic energy that consumes energy, thus improves building or antivibration capability of bridge.The present invention adopts the steel plate of disc-shaped structure to be combined with each other with friction solid damping layer, this damper can be arranged in various building and bridge construction, when horizontal earthquake occurs, due to damper upper and lower side generation relative displacement, just relatively rotate between supporting role lower disc shape steel plate, and owing to being filled with friction solid material between disc steel plate, thus just larger frictional damping can be produced between steel disc and friction solid material, reach the object of power consumption seismic energy.
Description
Technical field
The present invention relates to building science field, especially a kind of method and device improving building or antivibration capability of bridge.
Background technology
At present, the development trend of building is tall and bigization, the frame construction be made up of steel beam column, combined member or reinforced concrete member is frequent adopted form of structure in building, in order to the ability making building have the outside destroy such as stronger antiseismic or wind load, often need to arrange dissipative member in frame construction.Common dissipative member has Viscous fluid damper, MR damper and metal damper.Wherein, metal damper, because durability and better economy, has more application in engineering, and the external force that the metal damper adopted now bears according to its needs, have deformation in various degree.When the external force needing to bear is larger, then need larger deformation quantity, general size can require very large, so that processing, transport and installation are all very difficult, and the effect used is also undesirable.
Summary of the invention
The object of the invention is: provide a kind of method and the device that improve building or antivibration capability of bridge, its structure is simple, and processing, transport and installation are all very convenient, and energy consumption effect is remarkable, to overcome the deficiencies in the prior art.
The present invention is achieved in that the method improving building or antivibration capability of bridge, building or bridge are installed discoidal metal damping member, this metal damping member has the disc steel plate of more than three, friction solid damping material is filled between each disc steel plate, when being relatively rotated by disc steel plate, the frictional damping produced between disc steel plate and friction solid damping material reaches the object of the seismic energy that consumes energy, thus improves building or antivibration capability of bridge.
Improve the device of building or antivibration capability of bridge, comprise disc steel plate, disc steel plate is more than 3, is equipped with friction solid damping layer between each disc steel plate, and each disc steel plate and friction solid damping layer are linked together by axis; Outermost two disc steel plates are provided with two symmetrical outside field joints, one or two disc steel plate being in middle part is provided with two symmetrical middle part field joints.
In the circumference range of disc steel plate and friction solid damping layer, be provided with two or more with the adjustment tank of formed symmetrical, in adjustment tank, be provided with fastening bolt.Jointly play fixed disc by adjustment tank and fastening bolt and the effect of normal direction prestressing force is applied to disk, thus increasing the frictional force between disk and friction material.
When carrying out damper designs, first calculate the rigidity of disc steel plate, the lateral rigidity then required according to Practical Project just can determine the sheet number of steel plate, which increases the Out-of Plane Stiffness of damper, thus strengthens its lateral stability.
The present invention can carry out the size of damping adjusting by the thickness of the solid regulating friction solid damping layer, thus effectively can reduce structural vibration.Device of the present invention does not need to provide additional rigidity.Therefore, the natural vibration period of original structure can not be changed because installing device of the present invention, thus increase geological process.Relative to compared with viscoelastic damper, the impact of device excited target frequency of the present invention and temperature is less.These advantages make the present invention can be widely used in antidetonation and the wind resistance of engineering structures.
The material of friction solid damping layer of the present invention is specifically selected can the material of friction energy-dissipating, such as rubber, plastics damping sheet etc.
Owing to have employed technique scheme, compared with prior art, the steel plate of the employing disc-shaped structure of damper and friction solid damping layer be combined with each other by the present invention, this damper can be arranged in various building and bridge construction, when horizontal earthquake occurs, due to damper upper and lower side generation relative displacement, just relatively rotate between supporting role lower disc shape steel plate, and owing to being filled with friction solid material between disc steel plate, thus just can produce larger frictional damping between steel disc and friction solid material, reach the object of power consumption seismic energy.Method of the present invention is simple, and the apparatus structure adopted is simple, and with low cost, result of use is good.
