摘要
通过运用考虑几何非线性的结构弹塑性极限分析方法,对某山区高速公路桥梁中的钢筋混凝土高桥墩(H=45m)的极限承载能力及结构延性等进行了初步研究。分析结果表明由于高墩柱的结构存在几何非线性非常明显,采用通常线弹性方法计算在过大水平力作用下的墩顶水平位移将会带来相当大的误差,设计中应充分引起注意。主题词:复合非线性;极限承载能力;
In this paper, a hybrid non-linearity ultimate capacity and ductility analysis for RC tall-pier(H=45 m) of expressway bridges is studied The above study further shows that the regular linear-elastic analysis method in RC tall-pier design will causes quite-great errors when calculating the top-displacement of pier under a large horizontal force, as existing quite evidential geometric non-linearitility in RC tall-pier of bridges
