| Abstract: |
| Based on the open finite element system SiPESC.FEMS,a new general algorithm framework for structural time-history analysis is constructed by using C++ object-oriented programming method and software design patterns method,which considers the common features of time-history analysis algorithms.The core idea of the framework is that data model class and algorithmic class are designed individually.The whole framework includes four basic classes.The abstract process of the basic classes and the design idea of common interface are introduced,and the development process of the framework is given by employing the software plug-in technology.Furthermore,Newmark method,Wilson-θ method,central difference method and its improved method are implemented and numerical verifications are given.This investigation shows that the algorithmic framework has favorable extensibility and reusa-bility which is applicable to the general time-history analysis. |
