摘要
将普通圆钢管轴压构件分为大柔度及小柔度两种情况,对稳定系数与柔度的关系曲线分段进行拟合,并结合圆形钢管的截面特性近似计算公式,推导出近似柔度的计算表达式,从而提出了用于轴压构件截面设计的实用计算方法。算例表明,该方法避免了繁琐的试算过程,能简捷直观地得到满足稳定性要求的截面尺寸,可为实际工程设计提供参考。
Circular steel tube members are divided into two types such as long column and short column, and the curves of stability factor and slenderness are fitted according to two segments. The expressions for calculating approximate slenderness are derived by considering the cross-sectional characteristics of circular steel tube, and then a practical calculation method for cross-section design is presented. The calculated examples show that this method is simple and can avoid the pilot-calculation course; the cross-sectional dimensions meeting the requirements of stability design can be obtained easily. It may be a reference for engineering design.
