| 摘 要： | 工程结构中许多结构构件的受力可以简化为侧向弹簧支撑的压杆，应用基于样条函数的能量法求解弹簧支撑压杆的弹性屈曲临界荷载，由势能驻值原理推导了临界荷载的特征方程。算例表明，该方法未知量少，求解过程简洁，且精度较高。

| Abstract: | Many components in structures can model as lateral spring bracing columns,the paper solves the elastic buckling loads of bracing columns by spline function energy method,and derive the eigenvalue equations by using the principle of stationary total potential energy.Numerical examples show that the method have the advantage of less vectors,simplify and precision. |
