基于二硫化钼这种摩擦滑移材料,设计并制作了1种新型摩擦滑移隔震支座,通过对该滑移支座进行相关的摩擦因数试验,获得了该装置摩擦因数计算公式.利用ABAQUS有限元分析软件,建立了应用该新型摩擦滑移隔振装置的5层试验框架及相应抗震结构的有限元分析模型,并探讨了该抗震与隔震结构模型在EL Centro波3种地震烈度水平单向输入下的位移和加速度响应的主要规律.研究结果表明:该新型摩擦滑移装置使得框架模型在隔震层以上仅发生刚体平动且层间位移较小的同时,各层加速度响应较之对应的抗震结构大幅降低,从而有效地改善了该类结构的抗震性能,保护了上部主体结构.
Through comparing and analyzing whether or not the isolation technique is used for concrete frame structures by using ANASYS,the dynamic responses of the isolation structure in different field conditions and seismic intensities are studied,and the variation laws of the acceleration,displacement and interlayer displacement are analyzed.The study results show that comparing with the results of traditional seismic structures,the acceleration in the upper structure used with the sliding isolation structure is decreased obviously,the interlayer displacement is a little,and the pure friction as well as its residual displacement could not be neglected.All these as mentioned above could provide references for the research of the sliding isolation.
