摘要
本文因空间网格结构大位移理论分析的需要,详细推导出在节点大位移条件下,空间梁-柱单元的坐标转换矩阵。通过算例证明了本文理论方法的正确性。
In this paper, Ihe transformation matrix o(' the space beam-column clement is derived in detail to meet the analysis of space reticulated structures in case of large displacement of structuralj oints. A numerical example is given which shows that the theoretical derivation of the transformation matrix is correct and the computational work runs smoothly.
