[] Two isolator is a sufficient safety margin, the level of distortion does not affect the use of 250%, the other with sufficient bearing capacity to ensure the stability of the vertical support structures (Figure CJ-3), building isolation rubber bearings isolation layer structure with a stable elastic reset function can automatically reset the instantaneous multiple earthquake. This is a sliding isolation system which can not be compared. [Isolator] Third, to facilitate the design and construction. Because the building design and rubber bearing scientific and reasonable formula, compared with the traditional structure of the Sichuan earthquake rubber bearings manufacturers free design, the seismic response of the upper structure of the former reduced to about 1/4 to 1/8, safety reliability is greatly improved, fortified target architecture can generally improve a fortification level; traditional fortification goal is to "minor earthquake, the earthquake can repair, earthquake does not fall," and isolated buildings can be "minor earthquake bad, the shock is not bad not bad or mild, earthquakes do not lose the use of the function, "the potential economic and social benefits are very impressive, according to the construction experience, isolated structure is generally lower than the non-isolated structure cost 7% 15%. [Isolator] have an important influence on the seismic response of the building there are two main factors: one is the periodic structure, the other is the damping ratio. Stiffness in the general non-isolated low-rise buildings of large, short, just the basic cycle in the seismic input energy the greatest band. So far more than the corresponding acceleration of ground motion amplification reaction, but has a smaller displacement reaction, as shown by point A in Fig. If you extend the period of the building, while maintaining the damping constant, the acceleration response is greatly reduced, but the response was increased displacement. [Isolator] building seismic design methods currently seismic design methods are widely used around the world to consider the strength of both the good credit quality of isolation bearing manufacturers, but also consider the deformation and energy dissipation capacity. Has good ductility during seismic isolation bearing bridge design Nanning half promotions, proper control of the strength and stiffness of the structure, so that the structure under earthquake action into the inelastic state to dissipate earthquake energy input structure. This seismic design methods in many cases are valid. Rely on the strength of its own structure, deformation and energy dissipation capacity to resist horizontal earthquake, as artificially arranged some energy devices in the structure, but the structure of this type of energy system can only be effective when large deformations produced. [Isolator] In order to meet this need isolator, base isolation method came into being. [Isolator] parallel composite sandwich rubber isolator uses advance seat and sliding friction bearing parallel composite. Systems, advance seat mezzanine rubber provides the centripetal force to reset the system can automatically reset hysteretic energy friction sliding bearings with good energy dissipation capacity. This composite isolator combines the advantages of both front isolator, while also improving the shortcomings of a single isolator, which greatly improve the seismic capacity of the building structure is a simple, economical and effective has wide application value in the form of base isolation bearings. [] The use of the parallel composite isolation bearing isolator, gravity load of the upper structure can be shared by advances sandwich rubber seat and sliding friction bearings. This is a clear advantage: First, reduce the number of advance seat mezzanine rubber, natural growth cycle of the structure; the second is to reduce the yield shear increases the damping; third is to reduce the cost.
