摘　　要：介绍多种梁的挠曲线与其置换梁的挠曲线的关系研究,给出了求解各梁位移的置换法转角方程和置换原理中的转角连续性关系.鉴于对Γ型刚架的求解中稀有几何类方法的情况,运用所述的置换法和置换原理,把解梁问题的手段应用于该型刚架的解算.策划、归纳了求该型超静定刚架不同约束类型时的步骤.具体求解过程所用的计算为代数方程的分式四则运算,方法较通俗简便,结果是解析解.The research works on the relationship between the deflection curves of various kinds of beams and cantilever beam. It presents the equation of slope rotation angle by the conversion method and the continuity relationship of slope rotation angles by the principle of conversion. Owing to lack of geometric method for calculating frames with shape Г, the conversion method used to calculate the beams and the principle of conversion are employed to resolve the frames now. It puts forward the analyzing steps of the solution of statically indeterminate frame with shape Г by the conversion method and the principle of conversion. Different types of constraint are considered. The concrete process of calculation belongs to primary computation of algebraic equation. Easy to understand, it gets analytic solution.
