Description
Technical field
The present invention relates to a kind of protector of building, relate in particular to a kind of protector that reduces external vibration effects.
Background technology
Traditional civil engineering structure seismic design is come earthquake energy by the elastic-plastic deformation of structural element, reach the purpose that alleviates geological process, but the power consumption of the elastoplasticity of structural element can cause damage to structure inevitably, or even the damage that can not repair.The violent earthquake that is taken place in recent years is (as U.S. Northridge in 1994, nineteen ninety-five Japan Kobe, Taiwan Ji Ji in 1999, Chinese Wenchuan in 2008) the serious structural deterioration that causes and the heavy losses of property this defective that exposed traditional Seismic Design Method.
The passive energy dissipation technology consumes the seismic energy that was consumed by structural element (for example beam column node) originally, the distortion and the damage that have alleviated structure greatly by passive energy-dissipating device is set in structure.The energy consumer of having developed at present mainly contains four classes: friction energy dissipation device, metal yield energy consumer, viscous energy consumer and viscoelastic damper.Friction energy dissipation device is easier to apply with respect to other three kinds of modes in engineering because of its energy dissipation capacity is strong, stable performance, cheap.
Framework in the existing damping device generally adopts rectangular configuration, Chinese patent as notice of authorization on the 26th May in 2004, notification number is CN2617839Y, it discloses a kind of energy dissipating, vibration damping support device, comprise steel framework, supporter, damper, described steel framework is one with the building frame structure and is connected.In case when earthquake took place, this device can absorb, consume the energy of earthquake input, makes structure under the effect of earthquake, is in elastic state, reached the purpose of protection building.But because steel framework adopts rectangular configuration, device is easy to damage, and its power consumption is less, is not suitable for the application of super large and irregular building.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of damping control device is provided, its energy dissipation capacity is strong, is convenient to install, and satisfies the needs that engineering is used better.
For achieving the above object, the present invention adopts following technical scheme: it comprises quadrilateral frame and is arranged on damper in the framework, and damper is connected with framework by supporting member, and framework comprises upper and lower crossbeam and left and right supporting leg, and framework is a trapezium structure.
At the bottom of top rail was the minor face of ladder-shaped frame, at the bottom of lower transverse beam was the long limit of ladder-shaped frame, framework adopted isosceles trapezoidal structure usually.The gradient of left and right supporting leg is between 10 °-89 °, supporting member is connected on the upper and lower crossbeam of framework or/and on the upper and lower crossbeam that is connected framework and the node that left and right supporting leg is connected, be that supporting member has multiple connected mode with framework: 1. the damper center overlaps with frame center, supporting member is connected with frame joint, guarantees on two supporting members in top and the same straight line of damper diagonal; 2. the damper center overlaps with frame center, and the lower support member is connected on the underbeam, guarantees that four supporting members and damper diagonal are on same straight line; 3. four supporting members are arranged on the lower and upper cross-member, guarantee that four supporting members and damper diagonal are on same straight line; 4. the damper center overlaps with isosceles framework diagonal center, guarantees that four supporting members and damper diagonal are on same straight line.These four kinds of arrangements, first kind of arrangement is conventional arrangement, but first kind of arrangement and Pall damper arrangement mode are essentially different, the system that this arrangement constitutes is not the transition system, thus its energy dissipation capacity (gradient of isosceles trapezoid framework) its energy dissipation capacity is suitable with the Pall damper within the specific limits.Its excess-three kind arrangement has guaranteed that this system still is the transition system; its energy dissipation capacity is identical with the Pall damper; but wherein second, third kind connected mode helps in protection node damaged; and help the crossbeam power consumption; can protect the safety of structure, improve the reliability of structure at rarely occurred earthquake.
Supporting member adopts buckling-restrained support or frictional damping to support.Buckling-restrained support (BucklingRestrained braces, be called for short BRB) be that a kind of relatively more novel damping power consumption is supported, it is by supporting core and outside constraint mechanism constitutes, and has that anti-seismic performance is good, advantage of wide range of application, has obtained abroad using widely.Its basic design philosophy is to allow core bear axial force, a power is not born by external constraint mechanism, only play the effect that prevents to support the kernel flexing, buckling-restrained support is a kind ofly all can reach surrender but the supporting member of flexing can not take place under tension pressurized situation, and more traditional diagonal supporting member is compared has more stable mechanical behavior.
Damper and supporting member bolt.Supporting member and framework bolt or riveted joint or welding.
This device is easy for installation, be convenient to dismounting, and its energy dissipation capacity is strong, has shockproof widely, antidetonation application.
