摘要
采用Visual Basic 6.0高级编程语言,根据有限元理论和空间预应力索理论编制静力分析程序。对正放抽空四角锥网架的三种布索方案在考虑改变结构内力和减小结构变形两方面的计算结果分析比较,得到优化的布索方案。
According to finite element theory and the unit rigidity matrix of prestressed steel cable, the static analysis program is developed. It is made an analysis of three layouts of steel cables for the normally placed pyramid grids,by considering the change of structural internal force and deformation, an optical layout of steel cables is provided.
