【摘要】 近年来，异形柱空间框架结构CAD技术迅速发展，面向对象技术日益取代传统的结构化程序设计方法，成为现在及今后软件开发技术的主流。本文基于面向对象的软件开发原理，利用Visual C++6.0在Windows2000平台上开发了一套适用于异形柱空间框架结构设计的CAD系统——WFBCAD。文中详细介绍了系统的开发过程及功能，并阐述了面向对象的系统较结构化的设计软件具有明显的优势，这些表明将面向对象技术应用于结构工程CAD领域是极具现实意义和应用前景的。本论文研究的主要成果如下。 基于面向对象技术研究并实现了一套集数据、计算和画图于一体的异形柱空间框架结构类体系。本程序由于采取了把数据和函数封装成类的形式，数据管理方便，无冗杂数据。利用类的继承和多态特性，程序代码简洁，运行速度快。合理的组织和优化了系统的数据，减少了磁盘空间的占用和内存资源的使用。此外，本程序的类体系极具可扩充性，只要再添加剪力墙类和在其它类添加相应的接口函数，便可以扩充成框架—剪力墙类体系。 开发一个多文档—视图结构的图形操作界面。根据工程设计人员的使用习惯，本程序采取一条主工具条控制七条副工具条为主要操作界面，界面设计美观简洁。采用图形和文字相结合的工具条按钮，各按钮的操作一目了然，大大缩短用户学习使用本程序的时间。另外，本程序还提供了带截面尺寸示意图的对话框，使用户方便的输入尺寸数据。 完成了荷载的自动计算和异形柱配筋计算。程序自动输出柱配筋施工图。更多还原

【Abstract】 In recent years, with the rapid development of CAD technology for space frame structures with special-shaped columns, the object-oriented technology has gradually become the mainstream of soft ware development nowadays. The object-oriented CAD system for space frame structures with special-shaped columns (WFBCAD) has been developed on the platform of Windows 2000 in the environment of Visual C++6.0.The paper describes the development process of the system, its function and the advantages. The object-oriented technology applied in the CAD soft ware for structural engineering is of practical significance and has a good prospect of engineering application. In this thesis, several aspects as follows are studied.Based on the object-oriented technology, it is studied and realized that the class system, which encapsulate data, calculation and drawing, for frame structures with special-shaped columns. So its merits are favorable to data management and reducing miscellaneous data. By using characteristic of inheritance and encapsulation, code of programmer is more succinct, and speed of running is faster. Because data is rationally organized and optimized, use of disk space and memory is lesser. Besides, the class system is easy to be expanded. As long as adding a new class for shear walls, the class system can be applied to shear walls-frame structures.The program has a multiple document interface, which base on Microsoft Foundation Class Library. And there are 8 toolbars in the graphic operation interface. One toolbar is primary, and the others are accessorial. So the graphic operation interface is simpler and more beautiful. There are graphs and characters on the button of toolbars, which show use of button. So consumer can expediently use the program. Besides, WFBCAD supply a lot of dialog boxes which provided with sketch map of sectional size, so user easy input sectional size.The load has been automatically calculated in this program, as well as the reinforcing steel bar of special-shaped columns. The WFBCAD can automatically create working drawings of special-shaped columns.更多还原
