摘要
根据变截面压杆截面的变化规律,基于势能驻值原理,利用能量法推导出了变截面压杆稳定临界力的计算公式。该方法计算方便、精度高,适合于各种截面变化规律的压杆,易于被工程设计人员掌握。
According to the variation regularity of the column with variable section,the calculation formulas for critical bucking load of the column with variable section were derived by the condition of stationary value potential energy based on energy method.The method is not only accurate but also easy to use,and to be easily mastered by engineers.
