摘　　要：应用通用有限元程序ANSYS得到了不同情况下简支蜂窝梁的临界荷载值,分析了各种不同参数对其整体稳定性的影响;将有限元计算结果与能量法结果进行了比较,验证了有限元结果的可行性,可为工程设计提供参考。In different conditions, the critical load values of the simply-supported castellated beam are computed using the universal FEM program ANSYS, and influences of all sorts of different paramaters on the overall stability of the simply-supported castellated beam are analyzed. The comparison between the FEM result and the reference result is delivered,which validates the accuracy of the results of the FEM. Some useful conclusions are drawn for reference in the structural design.
