Solution of Slope of a Frame Based on Simple Support Beam Coming from Method of Changing to Rigidity by Step Combined with Conversion Method

摘要

The rigidity-step-change method is set up by Mechanics of Materials. Its distinguishing feature is at the steps of solving the deformation problem. It changes a deformation body to a rigid body before the solution of deformation of the body is get which fitting together with another. Then, step by step, it gets answer by Superposition Method. The main content of Conversion Method is at which the elastic axial line of the conversion beam substitutes the beam which being conversed. And the solution of deformation of the conversion beam could be found easily. In solving the elastic statically determinate frame, it uses the rigidity-step-change method and Conversion Method at suitable steps. It has good qualities for finding solution of the slope of the frame with simple support beam. Only primary computation is need. The steps of solution of the frame slope are given by an instance.
