LNG储罐预应力钢绞线束伸长值计算方法探讨

Exploration on elongation value calculation method of prestressed steel strand of LNG storage tank

通过对16万m3LNG储罐预应力钢绞线束的计算,详细介绍了国外预应力钢束理论伸长值的分段计算方法,并经过与国内算法比较,得出了精确计算预应力钢束伸长值对预应力施工控制的重要性。

Through calculating the prestressed steel strand of 0.16 million m3 LNG storage tank, the paper specifically introduces the sectional calculation method of theoretical elongation value of prestressed steel strand at home and abroad. By comparing to domestic calculation method, it finds out that accurate elongation value calculation of prestressed steel strand is rather important for prestressed construction control.
