| 摘 要： | 为了进行斜跨钢拱桥索梁锚固区主梁腹板内侧加劲肋的优选,以张家口某斜跨拱桥为研究对象,通过比选确定正确的计算单元和合理的计算梁段长度,采用有限元分析软件Ansys对锚箱式索梁锚固结构进行研究,并全面分析构造细节如加劲肋形式对锚固区各方面的影响。经分析得到腹板内侧焊接对应于锚固板和承压板的斜向加劲肋时,螺栓容易布置;焊接竖向加劲肋时,施工方便,二者都能满足分散应力的要求。

| Abstract: | An oblique-span steel arch bridge in Zhang Jiakou has been researched to optimize stiffeners inside of main girder webs at the cable-girder anchorage zone for oblique-span steel arch bridge.Correct calculation units and rational length of the cable-girder anchorage zone have been confirmed through analyses. And the model of anchoring box style cable-girder structure has been researched by finite element analysis software-Ansys.Different influence of the structural details,such as the forms of stiffeners has... |
