摘要
本文基于连续化模型和势能变分原理,得到矩形框筒结构的控制微分方程组,从微分方程组解得满足边界条件的位移函数,成功地统一解决了等刚度和阶梯刚度框筒结构分析的问题。
In this paper,based on the equivalent continuum model and the potential energy variational principle, the governing differential equations are obtained for the rectangular framed-tube structures, from which the displacement functions satisfying the boundary conditions are found. In this way, the problems of analysing the uniform and step stiffness framed-tube structures are solved and unified successfully.
