摘要
在利用计算机求解变截面框架形常数的基础上 ,用有限元的直接刚度法形成变截面框架结构刚度矩阵 ,再利用静力凝聚技术得到动力矩阵。由广义JACOBI法和规范振型分解反应谱法分别求解频率。
In utilizing computer to solve various section foundation of shape constant of frame.Forms and turns with the direct rigidity method of the finite element into the frame structure rigidity matrix of various section;and then utilize quiet strength condense technology of static power to receive power matrix. Use broad sense JACOBI method and shaking type decomposition reaction talble of the standard to solve frequency,shaking type and earthquake power.
