摘要

根据粘弹性阻尼器和摩擦阻尼器各自的特点 ,设计出一种新型粘弹性摩擦阻尼器 (FVD)耗能装置 .针对粘弹性材料的分数导数模型和摩擦单元的力位移滑移量的矩阵关系式 ,建立了FVD精确的有限元模型 ,推导了FVD单元刚度矩阵和控制力向量计算公式和求解方法 ;根据钢筋混凝土框架结构的非线性特性 ,建立了设置FVD非线性钢筋混凝土框架结构地震反应时程分析的控制方法 .最后 ,应用本文方法 ,对设置FVD的非线性钢筋混凝土框架结构进行了在罕遇地震和多遇地震作用下的时程分析 ,并根据计算结果对其减震效果进行了分析讨论 .
Based on the characteristics of viscoelastic damper and friction damper,a new friction-viscoelastic damper (FVD) is proposed. According to the fractional derivative model of viscoelastic damper and force-deformation-slip relation of friction element,a precise finite element model of FVD is constructed,and the method for forming element stiffness matrix and control force vector of FVD is deduced. Consequently,a time history analytical method is employed to analyze the seismic responses of nonlinear frame structure equipped with FVD under disastrous and minute earthquake.
