Numerical simulation of substructure hybrid simulation test method for the scale model

Abstract:

This paper proposed the hybrid simulation test method based on the similar theory for the scale model to reduce the cost and improve the efficiency of the experiment. The proposed method deduces theoretically the similarity conditions of both displacement and force under the identical material between the model and the prototype. The obtained similarity conditions are only used for the physical substructure. The parameters of both the motion equation and the numerical substructure are not changed. So it is easy to use the proposed method for the hybrid simulation testing method. Using the mixed programming method of MATLAB and OpenSEES, this paper realizes both the tradition substructure test method for the scale model, including shear model, bending-shear model and bending model, and the distribution substructure test method for the scale model. Compared with the numerical simulation results of the corresponding full scale model, the proposed method is validated.
