结构稳定性问题的级数解

Use the Method of the Infinite Series to Solve the Problem of Structure Stability

介绍用级数解狭长矩形截面梁的侧向屈曲 ,以及计算沿轴向实体线性变截面受压杆的临界荷载。

This paper introduces the solution of the lateral buckling of a simply supported beam with the narrow rectangular cross-section.It also explains the calculating of the critical load that the bar has varied from the linear cross-sections along the longitudinal axis.The result of using the method of the infinite series shows that is valuable theoretically and practically.
