变截面箱形薄壁立柱扭转屈曲荷载的近似分析

An Approximate Analysis for the Torsional Buckling Load of a Thin walled Box Column with Variable Section

本文利用虚位移原理导出了变截面箱形薄壁立柱约束扭转屈曲荷载的近似计算公式。利用这些公式,可使计算在PC1500台式计算机上实施,且程序短,结果精确。

Employing the principle of virtual displacements, approximate formulas for the torsional buckling load of a thin walled box column with variable section are derived. Using these formulas, the calculation can be implemented in the computer PC 1500 with shorter programme and accurate resulut.
