Calculation Module Programming For Spatial Reticulate Structure

Cooperating with several of my closed friends, we have developed a professional software for reticulate structure analysis and design. I have participated in the system analysis and mainly responsible for the programming of calculation module. From the viewpoint of OOP(Object Oriented Programming), this paper discussed the theory used in analysis of reticulate structure, and how to implement it in programming. At the end, a example is resolved in both our software and Ansys and comparison of the results is provided. Some useful research has been done, about which programming a steel special reticulate structure software, intelligent as well as specialty. This software is developed under the developing environment of VC++6.0. The method of Object Oriented Programming was been adapted. We derive user interface class from the Microsoft Foundation Class library, such as dialogs and resources, and derive entities from ObjectARX class library, and customize some class used to do other functions. In this way, we can concretize the data and the operation on those data. This paper includes five parts. Chapter one, a brief introduction of spatial reticulate structure, include the form of the spatial reticulate structure the load type considered and load combination; chapter two, the theory of calculation, include the description of the theory of FEA and the implementation of it; chapter three, class hierarchy analysis, it describe the derived relationship of costumed structure classes; chapter four, a example resolved in our soft is provide; chapter five, the author summarizes the research and points out some suggestion for the deeper research.
