【摘要】 国家体育场是迄今为止国内最复杂的钢结构工程,空间弯扭箱形截面构件、带过渡段的屋面主桁架弦杆、主桁架K形节点等是深化设计工作的难点部位。该文研究了复杂结构部件的几何构造特点,在AutoCAD图形平台上以ObjectARX和C++语言为工具,开发了专用的钢结构三维建模和详图放样软件系统。实际应用证明,该软件解决了弯扭构件展开放样等关键技术问题,提高了深化设计工作的效率和准确性。更多还原

【Abstract】 National Stadium is so far the most complex steel structure project in our country.Structural components,such as spatial curve-twisted box-section member,roof main truss chord with transition segment and roof main truss K-shape joint,are the difficulties of detailing design work.This paper researched the geometric configuration characters of these complex structural components,and based on AutoCAD graphics platform,with ObjectARX and C+ + language as tools, developed a specialized software system for the steel structure 3D modeling and detailing template-drawing.Actual application demonstrated that this software solved key technical problems,for instance deployed template-drawing for curve-twisted member,and thus enhanced the efficiency and precision of detailing design work.更多还原
