Background technology
Frcition damper is as a kind of energy-dissipating device, and because its energy dissipation capacity is strong, load, frequency are little to its performance impact, and simple structure, draw materials easily, cheap, thus there is 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 or 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 has developed multiple frcition damper successively, and its frictional force size is easy to control, and can determine conveniently by adjustment pretightning force size.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 caused comparatively large, also easily cause energy consumption effect significantly to reduce, and also easily cause the inefficacy of device.Therefore needing to carry out frcition damper perfect further, mainly by improving area of friction surface, the reliability of damper can be improved.
Summary of the invention
The object of the present invention is to provide a kind of lead dot to lock frcition damper, improve damping force by the quantity and area increasing friction plate, increase initial stiffness by arranging lead dot, and significantly increase power consumption.Initial stiffness and damping is adjusted by increase and decrease lead dot and replacing lead dot.Lead dot being locked frcition damper is installed on architectural; the integral rigidity of building structure can be increased when using in normal state; thus when running into earthquake; the power consumption utilizing lead dot to lock frcition damper can reduce the earthquake response of building structure, plays a very good protection to building structure.
