摘　　要：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,拼弃了按传统设计的折减系数法。并考虑了残余应力对压柱的实际影响,用直接荷载法对压柱截面尺寸进行了设计,该方法避免了多次的重复试算工作,通过算例显示了其简捷的优越性。A new stability criterion for the design of cross section of compressed solid columns was proposed based on Euler's formula of critical load, instead of the reduced coefficient method employed in conventional design. With this direct load method and by taking into account the effect of residual tress on the stability of compressed column, a practical design for the cross section area of compressed column was conducted. It shows that the new method has concise calculation steps and avoids the trial and error process.
