本文针对小型计算机的特点,对结构动力响应分析提出分离非线性单元、建立质量解偶且没有总刚度矩阵的运动方程及使用加速度脉冲外推法解非线性微分方程等重要措施,大大节省了计算机存贮量及计算时间.按本法已编制了计算机程序,通过算例验证了方法和程序的正确性. In this paper, according to the characteristics of small computers, some important measures such as separating nonlinear elements, establishing motion equations without mass stiffness matrix and using acceleration pulse extrapolation method to solve nonlinear differential equations are proposed for structural dynamic response analysis. Storage and calculation time. A computer program has been compiled according to this Law. The correctness of the method and program has been verified by an example.
