摘要
针对目前结构设计软件在自由曲面网格结构建模中的风荷载输入与构件截面角度调整中遇到的问题,基于自主研发的通用钢结构设计软件USSCAD,利用C++语言与ObjectARX技术创建了一种辅助面类,并详述了该辅助面类的属性以及辅助面的生成技术与应用原理.最后以某空间网格结构发电厂冷却塔为例,利用辅助面调整其构件截面角度,并将风荷载转换成等效节点荷载.结果表明,利用该辅助面可有效地进行构件截面角度调整与风荷载转换等效节点荷载,明显提高结构设计效率.
Based on the problems of inputting wind load and adjusting beam section orientation w hile modeling lattice shell of free form surface by means of structure design software ,an assistant face class was created by C＋ ＋ and ObjectARX .The generating technique and application principle of the assistant face were detailedly specified .The assistant face was also applied to CAD modeling of a cool‐ing tower ,correctly inputted wind load and adjusted beam section orientation .It can be concluded that the assistant face can evidently improve the efficiency of structural design .
