Description
Technical field
The utility model relates to a kind of building structure shake control device, particularly relates to a kind of disc type friction energy-dissipating damper of building structure shake control.
Background technology
Frcition damper is as a kind of energy-dissipating device, and because its energy dissipation capacity is strong, load, frequency is little to its performance impact, and simple structure, draws materials easily, cheap, thus has good application prospect.Particularly in the reaction of control structure near-fault ground motion and structural seismic response on the middle and senior level, there is unique advantage.Frcition damper to the mechanism that structure carries out vibration isolation is: produce slippage or distortion under the pre-constant load of damper before primary structural member surrender, rely on friction and Damping work seismic energy, simultaneously, because natural vibration period after malformation lengthens, reduce Seismic input, thus reach the object reducing structural seismic response.
The development of frcition damper starts from late 1970s, and subsequently for adapting to dissimilar building structure, Chinese scholars develops multiple frcition damper successively, and its frictional force size is easy to control, and can determine conveniently by adjustment pretightning force size.Frcition damper both may be used for the seismic design of new construction structure, also may be used for the strengthen maintenance of existed building, had good economic benefit.
At present, the frcition damper of research and development mainly contains: conventional friction damper, Pall frcition damper, Sumitomo frcition damper, fricting shearing hinge damper, slide type elongated hole bolt joint damper, T-shaped central layer frcition damper, pseudo-viscous frictional damper, multi-stage friction damper and some friction composite energy dissipation devices.
If the power that frcition damper provides is excessive, just need to improve normal pressure, the parameter error of calculating therefore can be made comparatively large, also easily cause energy consumption effect significantly to reduce, and also easily cause the actual effect of device.Therefore needing to carry out frcition damper perfect further, mainly can improve the reliability of damper by increasing area of friction surface.
