| 摘 要： | 以钢管混凝土系杆拱桥--郑州黄河公路二桥为背景工程进行斜吊杆试设计.采用有限元分析方法,研究了在不同吊杆布置形式下拱桥结构内力和挠度的变化.分析结果表明,斜吊杆的夹角对桥梁内力影响较大,设计时吊杆夹角的选取是一个重要的问题;采用斜吊杆替代直吊杆,可使拱肋和系梁弯矩减小,桥面挠度减小;在3种斜吊杆布置形式中,以径向吊杆布置的性能最佳.

| Abstract: | A trial design research on a concrete filled steel tubular(CFST) bowstring arch bridge with inclined hangers is conducted,which takes the Second Yellow River Bridge in Zhengzhou as a prototype.Based on finite element method,the influences of various arrangements of hangers to internal forces as well as deformations of the structure are studied.The results show the angles of the hangers play great roll in the structural internal forces,and it is important to choose a reasonable angel of hangers in design.If ... |
