Finite Element Analysis For Interaction Of Superstructure Raft Foundation And Soil Via Object-oriented Approach

The subject about interaction of the soil-foundation-superstructure system is paid attention to by more and more scholars. As a result, many models and calculating methods are put forward to deal with all kinds of problems, due to the complexity of the subject. In this paper, a calculating method was put forward after comparing some models, and analyzing factors of interaction of the system. In the meanwhile, a program is designed according to the method. With the development of computation, the finite element method gradually becomes a popular tool in engineering investigation and application. The traditional way of Process-Oriented- Programming has many disadvantages in readability, code use ratio, exploitation period, maintenance and so on. Therefore combination of the finite element method and Object-Oriented programming method has become a tendency in the filed of geotechnical engineering. In this paper, the basic components such as Node, Element, Load classes in finite element analysis model are abstracted and identified and the Object-Oriented programming of finite element software OOPFE(Object-Oriented programming of finite element )with VC++ is developed. The writer hope that the design would provided a basic platform for further research and developing.On the basis of related literature at home and abroad, this paper puts emphasis on studying the deformation behavior, internal force of raft foundation and superstructure. Case study show that the object-oriented model presented in this dissertation is correct and feasible, and the result is also satisfying.
