本文将六四式军用梁的标准三角和端构架各作为一个单元进行分析 ,得出单元刚度矩阵及坐标变换矩阵 ,介绍用六四梁拼组结构刚度矩阵的组集方法。将此方法的计算结果与传统桁架模型的计算结果进行比较 ,对拼组结构的强度设计理论进行讨论。
In this paper, the standard triangles and end frames of June 4 military beam are each analyzed as a unit, and the unit stiffness matrix and coordinate transformation matrix are obtained. The set method of the stiffness matrix of the 6 4 beam assembly structure is introduced. The calculation results of this method are compared with those of the traditional truss model, and the strength design theory of the group structure is discussed.
