本文通过对应用现有的大型有限元软件进行模拟、计算,得到不同的吊索张拉力对主梁应力的影响,结果表明,三对吊索索力同时有误差和单对吊索索力有误差表现出最大应力点的叠加关系。
In this paper, by using the existing large-scale finite element software to simulate and calculate, the effect of different sling tension on the girder stress is obtained. The results show that the error of the sling force of the three slings and the sling force of a single sling The maximum stress points superimposed relationship.
