摘要
介绍一般梁的挠曲线与悬臂梁的挠曲线的关系研究结果,给出了求解各梁位移的置换法原理.鉴于对铰支Γ型刚架的求解中稀有几何类方法的情况,运用所述的置换法,把解梁问题的手段应用于Γ型刚架的解算.具体求解过程是依挠曲线的连续性借置换法位移方程处理,所用的运算为初等计算,较简便易记,结果是解析解.即提出了一种解铰支Γ型刚架的新方法.
The research result of relationship between varied deflection curves with diffrent cantilevers is introduced. The principle of the conversion method for solving the displacements of beams is given. In view of lack of geometrical method solving the frames with shape F and constraint hinges,the conversion method which is used to solve beams now is used as a way solving this type of frames.According to the continuity of deflection curve and the conversion method, the concrete process of computation is the fundamental arithmetic operation, which is easy to remember. The result is an analytic one.A new way to interpret the type of frames is deduced.
