并联剪力墙地震反应分析的样条函数方法

A spline function method for seismic response analysis of coupled shear walls

本文根据并联剪力墙振型分解的地震反应控制微分方程,构造三次样条基函数,用样条函数方法对并联剪力墙进行地震反应时程分析,建立样条最小二乘法和样条伽辽金法的时程分析计算格式。本文方法所建立的动力刚度矩阵的半带宽仅为4,计算简便、易于编程,是一个简便、有效的分析方法。

In this paper, a spline function method is developed for seismic response analysis of coupled shear walls and a process of evaluation is established. The bandweath of the stiffness matrix established by this method is only 4. An example is worked out with 3 vibration modes. The numerical results show that the method presented in this paper is a simple,economic and effective method.
