摘要
利用ANSYS有限元软件对某悬索斜拉组合体系桥梁的锚箱式钢桥塔进行了特征值屈曲分析,得到了桥塔的稳定安全系数,探索了横隔板和竖向加劲肋对桥塔稳定性的影响,通过改变横隔板和竖向加劲肋的数量和布置,对桥塔的局部稳定性进行了优化设计,优化后的模型既能满足稳定性要求,又节省了材料。
This paper made eigenvalue buckling analysis on anchor box steel tower to a suspension cable-stayed combination system bridge based on ANSYS finite element software, obtained the stability safety factor of bridge tower, explored the influence of diaphragm and vertical stiffening rib to tower stability, through the change of number and arrangement of diaphragm and vertical stiffener, made optimization design to local stability on bridge tower, the optimized model could satisfy the stability requirement, but also saved the materials.
