钢管砼拱桁架架设斜拉扣索最优扣点探讨

Optimum cable point analysis for erecting CFST arch truss

根据“零弯矩法”概念 ,给出在拱肋节段吊装中关于扣索索力的计算公式 ,在此基础上讨论了扣索扣点最优位置、索力与扣点位置、塔高、塔距的关系 。

This paper gives out a formula for calculation cable force according to concept Zero Moment,and discussing cable optimum point,the relation to cable force,cable point,tower height and tower distance.An example is given about a CFST arch at last.
