摘要
在实际工程刚架结构中,为了减轻结构重量或满足生产需要,往往有些杆件采用变截面。在结构力学中只研究等截面杆件,不讨论变截面杆件。如何用结构力学方法来解决变截面异性材料刚架结构问题是文章讨论主要任务。实践表明变截面杆件的函数积分比较困难,如果借助Mathematica软件进行数值计算则十分方便。
In the practical engineering frame structure, in order to reduce weight structure or meet the need of the production, often some rods with the variable cross - section. In the structure mechanics research section only rods, didn＇ t discuss cross - section bar pieces. It is main task how to use structure mechanics method to solve the cross - section of the opposite sex material frame structure problem discussed in this paper. Practice shows that the cross - section bar a function integration is more difficult, but if by Mathematica software numerical calculation it is very convenient.
