摘　　要：拼弃传统设计的折减系数法,并考虑了残余应力对压柱的影响,直接以欧拉临界力为基础,建立起压柱新的截面设计稳定条件。用直接荷载法对截面尺寸进行设计。该方法避免了采用试算法的反复运算,并通过实例说明了新的设计方法的优越性。Abandoning the traditional discount coefficient method of design, considering the influence of remaining stress to pressure-poles, and based on the critical force directly, it builds a new steady condition of design for pressure-pole's section. And it designes the section size by direct load method, which avoided to abopt the trial-calculating method of counting repeatedly, also showed the superiority of new design method by cases.
