【Abstract】 A kind of connecting element and connecting substructure are presented in this paper. They can be used to solve a structural system which has weakly connected components and deformes discontinuously. Combined with the modal synthesis technique, the coupling transformation between the substructures may be very simple. Using the parameter identification method, the stiffness coefficients can be obtained with sufficient accuracy and a small amount of computation.更多还原
