本文简要综述了结构矩阵分析中的一个重要的变换关系——逆步变换,对几个应用实例作了讨论和分析,文中最后介绍了在解决实际结构计算问题时,藉助逆步变换而导出的一个过渡单元——墩柱单元的刚度分析公式。
This paper briefly reviews an important transformation relationship in the structural matrix analysis—reverse step transformation, and discusses and analyzes several application examples. In the end, the paper introduces the use of reverse transformation to derive the solution to the practical structural calculation problem. A transition unit - the stiffness analysis formula of the pier column unit.
