本文采用层间剪切模型对多、高层二阶摩擦减振控制支撑框架进行了动力分析。分析中，将这种框架的总刚度矩阵分解成线性和非线性两部分，采用Ｗｉｌｓｏｎ－θ法求解动力方程。基于该方法编制了层间剪切型串联多自由度体系的时程分析程序。通过算例表明，该程序具有较高的准确性，可用于二阶摩擦减振控制支撑框架结构的地震反应分析。
In this paper, the dynamic analysis of multi- and high-level second-order frictional vibration control support frames is performed using the inter-layer shear model. In the analysis, the total stiffness matrix of the frame is decomposed into two parts, linear and nonlinear, and the Wilson-θ method is used to solve the dynamic equation. Based on this method, a time-history analysis program for the inter-shear shear series multi-degree-of-freedom system was developed. The numerical example shows that the program has high accuracy and can be used for seismic response analysis of the second-order friction damping control frame structure.
