Abstract


Isolation , including base isolation and interlayer seismic buildings isolation at home and abroad , at present, mainly refers to the base isolation . With the deepening of the research and application of base isolation , base isolation gradually shows its drawbacks , and to limit the the isolation technology development , interlayer seismic isolation technology development . The paper analyzes the interlayer seismic structure work mechanism and application of dynamic response equations simplify interlayer seismic structural system . For the level of ordinary laminated rubber bearing low lateral stiffness and the large deformation restore the poor inadequate , the use of super- elastic properties of the material of the shape memory alloy (SMA) SMA strands around ordinary laminated rubber bearings installed on the diagonal , to design a new type of damping energy dissipation devices -SMA composite bearings . SMA compound bearing isolation effect of changing the structure works and theoretical analysis , the establishment of a dynamic analysis model based on SMA compound bearing interlayer seismic structural system to determine a method for solving . Through the establishment of the of interlayer seismic structure system three-dimensional finite element model , and numerical comparison analysis in the ordinary laminated rubber bearings and SMA compound bearing situation INTERLAYER earthquake structural system to verify the damping effect of SMA compound bearing . The results show that : (1) SMA the stranded improve the the ordinary rubber bearings stability and poor recovery shortcomings . Around in ordinary laminated rubber bearing installation the SMA strands can improve bearing horizontal lateral stiffness allows the holder to occur through the horizontal shear deformation and restored to its original position and maintain the stability of the bearing . ( 2) layer isolation structure can effectively extend the vibration period of the building , structure deformation is focused on the isolation layer , isolation layer is set lower , the better of the interlayer seismic and convenient construction , is a with the development of future shock absorption system . (3) apply the SMA compound bearing interlayer seismic structure compared with ordinary laminated rubber bearing with better isolation effect . SMA compound bearing an effective isolation device , SMA compound bearing used in interlayer seismic isolation system , which have good isolation effect .
