【摘要】 本文提出一种轻型钢结构的三维设计方法，着重研究节点和节点 板的智能设计方法。在该方法中，首先通过交互手段输入轻型钢结构 的三维线框简图、自动确定结构的几何和拓朴信息，根据设计要求输 入各杆件的型钢类型和在结构中的功能；然后，根据型钢类型、杆件 功能、钢结构设计知识以及焊接知识自动确定杆件的搭配关系、建立 杆件的方位布置确定规则和节点板设计的规则；最后，利用这些规则 来决定节点秆件连接关系、连接位置，确定节点板的类型、布置方位 和位置，实现三维钢结构的结构自动设计。采用面向对象的技术建立 轻钢结构的计算机表示模型，利用ObjectARX开发平台开发了一个轻 钢结构自动设计的原型系统并通过了几个实例验证。更多还原

【Abstract】 A design approach to the 3D design of light steelwork is presented in this thesis. The intelligent design of the steelwork joint type and joint plate are studied. The design process of the proposed method is described as follows: the input of the method is the 3D sketch of a light steelwork, and the geometry and topology information of the members in a steelwork are established automatically. The steel types and function of the linked members are determined by means of interactive scheme according to the design requirements. And the arrangement of the steel members and their orientation are built according to the steel member’s type, the function of the steel member, the knowledge of the steelwork and welding technology. Based on the above requirements and design knowledge, the design rules of the steelwork joint plate are established, and the joint locations, the type and the orientation of the joint plate are determined according to the design rules. Based on the oriented-object technology, a computer model of the light steelwork is established and a software prototype system of the intelligent design for light steelwork is developed by ObjectARX2000.更多还原
