| 摘 要： | 根据粘弹性阻尼器和摩擦阻尼器各自的特点，提出一种新型粘弹性－摩擦阻尼器（F－Ved）耗能装置，推导了粘弹性－摩擦阻尼器和人字型支撑的阻合层间单元刚度矩阵和控制力向量；并基于框架结构的空间特性，建立了设置（F－Ved）框架结构在考虑空间协同分析的基础上地震反应时程分析的控制方法，应用此方法，对设置F－Ved的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，并根据计算结果与其减震效果进行了分析讨论。

| Abstract: | Based upon the characteristics of viscoelastic damper and friction damper,a new viscoelastic friction damper (F Ved) is proposed.This device uses viscoelastic materials to dissipate vibration energy when the structure is excited by minute earthquake. Based upon the fractional derivative model of viscoelastic damper and force deformation slip relation of friction element, a precise finite element model of F Ved is constructed, and the method of forming element stiffness matrix and control force vector of F Ved is deduced in this paper. Consequently, a time history analysis method for earthquake excited damped structures is developed. |
