摘要
首次在铁路矮塔斜拉桥主梁中采用波纹钢腹板箱梁,对这一新型结构型式进行了方案设计和全桥有限元静力计算,着重分析了波纹钢腹板的应力情况,并对其局部、整体和组合三种剪切屈曲模式进行验算分析,给出其应力分布规律和受力特点。
In thi s paper,a design of extradosed bridge with corrugated steel webs,the first attempt in railway bridge,was made,spatial finite element static analysis and local,global and interactive shear buckling analysis were done,and the distribution of stress and behaviors under loading were given.
