摘　　要：在吕西林等人研究的基础上 ,建立面向设计的摩擦耗能框架结构弹塑性的时程分析方法 .该方法中钢筋混凝土框架整体结构采用层间剪切模型 ,柱采用四线性恢复力模型 .柱模型的骨架控制点参数由 M- φ非线性计算程序计算 ,摩擦耗能装置的恢复力模型采用理想弹塑性模型 .文中利用 VC+ +编制相关的程序 IDAFF,该程序考虑 P- Δ效应 ,同时给出一个分析算例 .Starting from studies of Lu Xilin, et al, the authors establish a design oriented method for analysing elastic plastic time history of a frame structure with frictional energy dissipation. In this method, an inter floor shear model is adopted for the whole RC structure; and a quadrilinear recovery force model, for the RC inter floor columns. The parameters of control points on the framework of the quadrilinear recovery force model are calculated by M φ nonlinear calculator program. An ideal elastic plastic model is adopted for the recovery force model of frictional energy dissipating device. This method is described in detail, the dependent program IDAFF is developed by using VC ++ language and the P-Δ effect is considered in the program. Moreover, an analytical example of calculation is given.
