摘要
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。
This paper analyses the '64 Type' beam unit as a finite element. Its element stiffness matrix and coordinate switch matrix are obtained, and then the method of assembling primitive stiffness matrix of the structure is introduced. Comparing the calculation results of a simply supported beam assembled by '64 Type' beam units and that of the truss model, the theory of strength design is discussed.
