This method reduces the complexity of computation by subtracting the initial state of the base structure, which avoids the problem of calculating all structure displacements in traditional methods. At the same time, this method improves the calculation accuracy by considering material and geometric nonlinearity.This paper mainly includes the following parts: firstly, the basic principles of structural dynamics analysis and the problems existing in traditional calculation methods are introduced; then, the principle of substructure method is briefly introduced; then, the proposed computation method based on substructure method is introduced in detail, and the specific implementation steps are given; finally, the effectiveness and accuracy of this method are verified through numerical experiments.【Keywords】structural dynamics analysis; substructure method; real-time computation; nonlinearity
