【摘要】 本文提出一种以Ｃ＋＋库的形式建立的现行检结构设计规范的面向对象模型。该模型作为一种规范库与应用程序相对独立，这样，一方面便于设计规范的单独维护与更新，另一方面能使规范库供多个应用程序使用。另外，利用Ｃ＋＋类定义与其实现代码相分离的特点，代码可以有不同设计规范的实现版本，这样同一个应用程序有可能通过统一的接口使用不同国别的规范。文中描述了规范库类等级关系的设计并结合示例说明了规范库的使用方法。更多还原

【Abstract】 This paper presents an object oriented model of current design standard of reinforced concrete structures.As a kind of design standard base,the model can be isolated from application programs in CAD systems.The isolation means that the design standard can be not only maintained and updated.independently but also used in any application programs to which the standard apply and especially suitable for integrated CAD system development.Meanwhile,owing to the separation of class definition and its implementation,the implement programs could have different versions from different design codes,which promises a possibility of development of multistandard CAD system. The class hierarchy of the design standard are described and the usage method is illustrated by some examples.更多还原
