Development of an Object-Oriented Program for Structural Collapse Analysis of Framed Structures

Development of an Object-Oriented Program for Structural Collapse Analysis of Framed Structures

The object of this project is to develop numerical analysis code using vector form intrinsic finite element(VFIFE, or V-5) method. In this work, this code design and implementation of an object-oriented technology. The code name is called SUV-5 which has a user friendly interface to simulate nonlinear static analysis, nonlinear dynamics analysis and collapse analysis of structures. An easy-to-use and user-friendly interface was developed at the National Center for Research on Earthquake Engineering(NCREE). In this project, this interface is called GISA3D which has modified in the SUV-5. In addition, the project also has successfully developed a fiber section element. The element cross-section can be a fiber section using different stress-strain models. These materials include the reinforced steel, steel, well-confined concrete and not well-confined concrete. Finally, the accuracy of SUV-5 was demonstrated by comparing experimental and numerical results.
