Object-oriented finite element programming for reinforced concrete nonlinear analysis

Classes in object-oriented programming are made for the reinforced concrete nonlinear finite element structural analysis. The program developed in this paper is based on reinforced concrete nonlinear finite element structural analysis models and MFC (Microsoft Foundation Class Library). These classes include concrete element class, bar element class, bond element class and nonlinear element class. They construct a new reinforced concrete finite element analysis system, combining with other basic classes related to the concepts of finite element method. The descriptions and implement approach for the classes also are given in detail. All the work finished by this paper provides an approach to employ the more reasonable object-oriented programming for the reinforced concrete nonlinear finite element structural analysis.
