摘　　要：等边单角钢广泛应用于工程结构中，在此类构件承受轴向压力及同时承受压力及弯矩情况下应考虑其整体的稳定性。通过理论及相关适用于工程应用的计算公式对等边角钢构件的稳定性进行分析，确定受轴向压力时的屈曲形式。为使构件最好地发挥轴向受压稳定性，计算出屈曲计算长度l、肢宽b及肢厚t三者之间的近似关系式。对复合受力情况下的稳定性进行简化分析。Equal angle steel is widely used in engineering structure. For member in compression and member in bending and axial compression, the whole stability should be considered. The stability analysis of equal angle steel member is carried out by theory and related calculation formula suitable for engineer/ng application to determine the member buckling form in axial compression. In order to make the member in axial compression hold the best stability, the approximation relationship among buckling length （1）, leg thickness （t） and leg breadth （b） are formulated. Stability of the equal angle steel member in combined load is studied also.
