| 摘 要： | 本文将空间梁单元的刚度矩阵视为梁截面的剪切形状系数的函数，对FRAME3相关子程序进行了适当改动。使该程序计入了截面的剪切形状系数对梁变形的影响，并将剪切形状系数视为变量进行了随机处理，利用算例求出了不计、计入剪切形状系数时杆系结构的解及其对剪切形状系数的随机解，并对三者进行了比较分析。

| Abstract: | In this paper, the stiffness matrix of three-dimensional beam element is regarded as the function of the shearing-shape coefficient of beam section . In order to measure the effects of the shearing-shape coefficient on the beam framework, not only some proper modification to related subroutines of FRAME3 is made in some ways making the program involves the shearing-shape coefficient effects on beam deformation, but also the shearing-shape coefficient looked as variable is treated in stochastic way. In the mean time,using the example, three-dimensional beam structural solutions of ignoring, including the shearing-shape coefficient and the stochastic solution about the coefficient are solved. At last, we compared with them and make some conclusions. |
