柔性吊杆张拉力的探讨

The discussion on tensile stress of flexible boom

对下承式系杆拱桥中使用柔性吊杆的张拉力进行了分析,发现各设计图纸的反映不同,没有规律性,且不符合抛物线拱轴的要求,故对如何确定吊杆张拉力进行研究。

The tensile stress of flexible boom adopted in through bowstring arch bridge is analyzed,the result is that design drawings react differently,no regularity is shown between them,and they do not meet the need of axis of parabola,therefore come this research on how to determine the tensile stress of boom.
