摘要
系统地介绍了加权残值法在直杆弹性稳定分析中的应用．算例表明，此法简单易行，可用于等截面直杆，也可用于变截面直杆，不仅适用于手算，且可用于电算．
The application of the method of weighted residuals in the elastic stability analysis of straight members is systematically introducd.Numerical examples show that it is easily applicable to members with either equal or unequal cross section and can be used not only in hand calculation but also in electronic computers.
