摘要
按照受压杆整体稳定性和其组成板件局部稳定性相当的等稳定性原则，详细计算了常用工字截面翼缘宽厚比ｂ／ｔ、腹板高厚比ｈ０／ｔｗ和压杆柔度之间的对应离散点值，提出了简化适用的拟合公式，供有关部门参考。
In accordance with the equivalence principle that the stability of the whole structure is equivalent to the local stability of the section flange, the values of the flexibility corresponding to the width to thickness ratio of section flanges, b/t and to the height to thickness ratio of web plates, h0/tw are calculated. A simplified formula for design is proposed.
