[Isolation] bearing isolation technology development and the principles outlined in the conventional seismic systems gradually cause problems in earthquake engineering scholars think. In order to adapt the structure of the earthquake, in recent years, people continue to find effective ways to resist earthquake damage, such as the development of new materials, research new structure and so on. [Isolation] bearing isolation technology is one of the hotspots of earthquake engineering practice. Now more research and application of seismic isolation technology is mainly laminated rubber isolation and sliding isolation. But most studies limited to a single study or a single seat mezzanine advances rubber friction sliding bearing. Since the development of composite isolation system is relatively late, no one has conducted in-depth research, design and thus the lack of adequate data points. [Isolation] base isolation bearings isolation layer is set between the upper structure and foundation, through isolation system isolation layer to restrict incoming and absorb the seismic energy structure. The following seismic response spectrum of the building to explain the principles of base isolation. General building acceleration response spectrum and displacement response spectra. As the general structure rigidity, short cycle, so when vibration acceleration large and small displacement. [Seat] isolation can be seen from the above, to extend the period of the structure, where appropriate, bridge rubber bearing quality assurance, can effectively control the acceleration of the building, if we give appropriate damping structure, the structure of the displacement also It can be controlled within the allowable range. [Isolation] big displacement bearing structure is mainly provided by the isolation system between the bottom of the structure and foundation, then it will effectively weaken the seismic energy input structure, but not too large to make structural deformation destruction . This is the basic principle of building base isolation bearings] [vibration isolation rubber bearing isolation technology of building isolation rubber bearing isolation technology of isolation bearing [] when an earthquake occurs, LRB Lead rubber bearing quality, to extend the period of vibration of the building structure by building isolation rubber bearings and give greater damping, so acceleration response structure is greatly reduced. At the same time, a larger displacement of the resulting structure is provided by isolation bearing the isolation layer, rather than borne by the relative displacement of the upper part of the structure itself, so as to avoid or substantially mitigate disasters caused by the earthquake. [Seat] building isolated isolation rubber bearings, isolation, damping, base isolation technology. [] Seismic isolation bearings is a great danger of random natural disasters, can cause human catastrophe. People struggle with their long process, constantly sum up experience, to seek a better earthquake disaster prevention measures to increasing development of seismic theory. At present, the traditional seismic techniques commonly used at home and abroad, the building isolation rubber bearings of high-tech enterprises, has produced a new seismic design theory and control structure structure control theory. Structure control, also known as active control, main control structural engineering design theory means, methods and implementation; [isolation] control structure, also known as passive holder control, rubber bearing, according to a given structure and conditions the control device as a whole to optimize the design. Since the active control constraints more expensive and other reasons, its applied research is still in its pioneering stage; and application of passive control is one hot topic in the international civil engineering industry. Among them, the base isolation structure passive control of the most important content of the full range of rubber bearing _ _ earthquake rubber block provided by the high-tech enterprise-Engineering Rubber Co., Ltd.
