| 摘 要： | 位移法是计算高次超静定结构的重要方法,等截面弯曲杆件的刚度方程是其基础。文章详细论述了刚度方程的两种推导方法,分析了两种推导方法的内在联系。这有助于更深地理解超静定结构相关内容,也可以进一步了解单位荷载法的应用。

| Abstract: | Displacement method is an important method to compute the high degree statically indeterminate structure.The stiffness equation of uniform section bending bar is the base of displacement method.The authors elaborate two methods of deriving the stiffness equation,and analyze certain logic to the two methods.It is helpful to understand more deeply the contents associated with the statically indeterminate structure,and know better the application of the unit load method. |
