    The invention provides a ship structure nonlinear response similar distortion scale model design method. The method comprises the following steps: S1, selecting an actual ship stiffened plate structure design prototype; the method comprises the following steps: S1, dividing a stiffened plate structure prototype into a plurality of stiffened design units by taking a single longitudinal girder or a single longitudinal bone as a unit, and S3, aiming at a first stiffened design unit prototype, scaling the stiffened design units in a size dimension and a plate thickness dimension; s4, converting the scale model in the step S3 into a yield strength and larger scale model, and recording the scale model as a first-stage scale model; s5, scaling the first-stage scaling model at a second same scaling sigma 2; s6, obtaining a second-stage scaling model; s7, repeating the steps S3-S6 to obtain a second-stage scaling model; and S8, combining the second-stage scaling model to obtain a scaling model. According to the method, the section size of each reinforcement on the stiffened plate scale model can be flexibly adjusted, so that the stiffened plate scale model is more convenient to weld and process, and the method has higher engineering application value.
