Abstract


As a new type of layer interval shock technology, it has common seismic technologyirreplaceable advantages, layer interval shock structure of the base-isolated structure isolationlayer set position limits, in the domestic and foreign many engineering cases are widely usedwith this new type of shock absorption technology. This paper USES finite element analysissoftware SAP2000, proposed isolation layer set in different locations of the structure model ofthe structure model for dynamic time history analysis, input pre-arranged different seismic waveson the structure model for seismic response analysis of contrast and make a summary, draw layerinterval shock structure damping effect and change rule, and at the same time, discuss isolationlayer position change, on the structural damping effect and change rule. Conclusion:(1) First to isolation device performance was summarized and classified, and theirperformance analysis and comparison, choose the most appropriate lead core rubber isolationbearing, and then the layer interval shock structure dynamic equations were built and solved.(2) The use of software proposed structure model, through to the isolation layer set indifferent position of the isolated structure model characteristic analysis: extend the isolationstructure of the basic cycle can well improve the structure under the action of earthquake shockabsorption effect, and the isolation layer set position is higher, the smaller the vibration period ofthe structure.(3) To five isolation layer set in different locations of the layer interval shock structure anda facility isolation layer of earthquake resistant structure model, and the seismic responseanalysis of the structure of the floor shear force and displacement and acceleration are analyzedin that: whether in the role of the earthquake or in Abraham in the role of the earthquake, thestructure of the seismic response of change law basic same. With isolation layer position moveup, isolation layer between layers of the displacement of isolation layer is reduced, in addition toother than floor displacement between layers of the increase. Through the analysis of thestructure that layer interval shock acceleration in the isolation layer position mutations, isolationlayer and the lower part of the adjacent structure floor acceleration obvious change, and part ofthe floor acceleration reduced, this means that structure setting isolation layer, the isolation layerabove the structural part has a very good damping effect, but for the lower structure but mayhave the effect of enlarge. So the isolation layer set the lower position of the whole structuredamping effect is better.
