摘要: 对大跨砼斜拉桥进行的稳定分析中,模拟了拉索只拉特性、施加了预应力与预拉力、考虑了材料非线性与几何非线性,得到了合理的计算结果

关键词: 斜拉桥, 只拉, 预应力, 非线性

Abstract: This paper draws a reasonable conclusion by calculation on the stability of the long span pre stressed concrete cable stayed bridges.All of the results are based on a finite element calculating model,in which the cables only tensioned property was simulated and the effects of the pre tension cables and pre stressed reinforcement are included.Furthermore,the effects of the geometric non linearity and material nonliearity are studied together.

Key words: cable stayed bridges, only tensioned, pre stressed, non linearity
