摘　　要：将二硫化钼(MoS_(2))涂层材料作为摩擦材料,以U型带片作为限位消能元件,组成新型摩擦滑移隔震装置,并将其应用于结构中,形成新型摩擦滑移隔震结构。采用SAP2000有限元分析软件,研究在不同限位刚度下新型摩擦滑移隔震结构基底滑移量及上部结构动力响应的变化规律。分析结果表明,新型摩擦滑移隔震结构三个代表层的加速度、基底剪力基本上随隔震层限位刚度的增加而增加,而基底滑移量总体上随隔震层限位刚度的增加而减小。结构三个代表层的加速度、基底剪力在某些隔震层限位刚度区段内呈现局部波动的现象。A new type friction-slip isolation device are composed of a new kind of coating material(MoS_(2))used as the friction material and Ushaped steel plate used as sliding-limited and energy-absorbed element.Variation of base slip and upper structure dynamic response of new type friction-slip isolation structure under different limiting stiffness is studied by SAP2000.The results show that acceleration of the three representative layers of structure and base shear basically increase with the increasing limiting stiffness of isolation layer,while base slip of structure decreases as a whole.Acceleration of the three representative layers and base shear force in some limiting stiffness section of isolation layer shows the tendency of local fluctuation.
