【摘要】 结合钢结构设计 ,在原有智能点定义的基础上 ,扩充了它的属性 ,使得它不仅可以方便地描述构件之间的内部关系 ,而且可以简单地表示构件之间的局部关系 .用扩充后的智能点对钢结构模型的拓扑结构进行了描述 ,智能点统一了模型构件之间的拓扑描述 ,使模型的表示更加简单 .在智能点分类的基础上 ,提出了多个智能外点约束属性的归并准则 .最后给出了利用遍历模型网状图进行杆件约束布置的算法 ,并给出了该算法的约束图实例 .更多还原

【Abstract】 Based on steel structure and the existed smart point, this paper extends the feature of the smart point. With the extended smart point, the local restrict of staffs in steel structure can be expressed. The topological structure of the steel structure is described by the smart point. A unity rule of smart points is presented. The algorithm about the traveling model graph to get the message of the restrict is given and the constrain diagram of a practical model elevation is also shown.更多还原
