空间预应力束伸长量的简化计算方法

结合实际工程,对曲线形梁桥空间预应力束的伸长量计算进行了探讨,并针对目前空间预应力束伸长量计算中的不足之处,在同时考虑竖弯和平弯产生预应力损失的基础上,提出一种简化计算方法,实践证明该方法方便有效,计算精度能满足设计要求。

On simplified calculation methods for space prestressed tendon length amount

Combining with factual projects,the paper explores the length amount of the curved beam bridge's space prestressed tendon,and points out a simplified calculation method by combining with the shortage of the space presstressed tendon length amount calculation and the prestressed loss caused by the vertical and horizontal bending,and proves the method is convenient and effective and the calculation accuracy can meet the design requirement.
