Background technology
Earthquake causes huge disaster to the mankind, and China is one of country that earthquake disaster is the most serious in the world. China is also the country that global earthquakes injures and deaths are maximum. When earthquake occurs, structure is absorbed by energy transformation or a large amount of seismic energies of dissipation Seismic input structure. Damaging occur in earthquake in traditional Aseismic Structure System admissible structure and component, and this damage process is exactly the consumption process of energy. Structural member power consumption is more many, then its destruction is more serious. And structure and component badly damaged or to collapse be exactly seismic energy conversion or finally completing of consuming. Energy-dissipating and shock-absorbing technology arranges energy-dissipating device at some position of structure, the most of energy being dissipated by energy-dissipating device or absorbing in Seismic input structure, to reduce the earthquake reaction of agent structure, alleviates earthquake to the damage of agent structure. Sinker has metal sinker, friction energy dissipation device, viscous damper, the sticky bullet type such as sinker, buckling-restrained support. Metal sinker, buckling-restrained being supported on rare meet earthquake when occurring, and bear cyclic reverse loading to the seismic energy that dissipates, and after shake, sinker is as produced residual set or damage, then need to change. The replacing of sinker is more difficult. Friction energy dissipation device simple structure, power consumption clear principle, energy dissipation capacity is strong, but it does not work under normal circumstances, and its friction pair is under long-term static load, it is possible to cold-adhered can be produced or condensation solid, become the focus of concern, govern the popularization of friction energy dissipation device.
