摘要
以连续化数学模型和能量变分原理导出的变截面高层框筒结构的微分方程组为基础;根据变截面框筒结构的截面沿高度为阶形变化的特点,以每个相同截面的层作为一个计算单元,每个单元由微分方程组导出其单元矩阵、截面矩阵和传递矩阵。进而采用传递矩阵法进行分析。此法概念清楚,计算简单。并以算例说明其应用。
The differential equations of variable section framed-tube structures are derived based on a mathematical model of an equivalent continuum and the energy variational principle. Every storey with a same section is taken as a calculation element. The element matrix, section matrix and transfer matrix of every element are derived by the differential equations. Then the variable section framed-tube structure is anlyzed by the transfer matrix method. Finally, a mumerical example is given.
