摘要
对体外预应力张弦梁结构在竖向荷载下的受力性能进行了系统的研究,通过理论分析给出了单向张弦梁结构合理预应力的计算方法,并对单向张弦梁的合理高跨比和上下弦刚度比进行了探讨.在此基础上,进一步提出了双向张弦梁结构合理预应力及高跨比的计算方法.
The mechanical behaviors of the externally prestressing beam string structure under vertical load are studied systematically. The reasonable prestressing force of a single beam string structure is determined with analytical theory. The depth-span ratio and the stiffness ratio between the upper chord and the lower chord are discussed also. As a result, the reasonable prestressing force and the depth-span ratio of the two way beam string structure are obtained accordingly.
