用能量法推证位移方程

Using Energy Method to Derive and Prove Displacement Equation

利用能理法原理 ,通过虚设一移动载荷或单位载荷的方法用卡氏定理或莫尔积分求得结构的位移方程。

Applying energy method principle,through a method of virtual supposing a moving load or unit load,the displacement equation of structure can be obtained by using A.Castigliano theorem or Moore integral.
