摘要：The numerical analysis based on the dynamic interaction of structure and foundation plays an important technical basis for the seismic evaluation of large-scale engineering structure in nuclear and hydraulic engineering field. But with the complexity increasing of the practice issue, the engineering solving scale becomes larger and larger, which will brings great difficulties for researchers to develop analysis programs in these fields. One difficulty just aims at the application solution method with wide range. On the basis of the large scale sparse matrix solution function of MATLAB, a VC++ and MATLAB mixed programming mode is presented in this paper, in which the total stiffness matrix of structure is numerically stored with only non-zero element data. The dynamic link library is applied as the interface media of MATLAB to solve the dynamic equilibrium equation. Finally, the validity of the proposed mode is verified in the form of some numerical examples.
