摘要
以一座大跨度钢系杆拱桥为工程背景,对不同吊杆布置形式下拱肋和系梁各关键截面的内力影响线进行了比较分析,对吊杆形式对结构竖向和横向刚度的影响作出评价,得出相对较优的吊杆布置形式。
Taking a large span steel tied arch bridge as the project background, it makes a comparison analysis of the internal force influence lines of the key cross sections of arch rib and tied beam under different laying ways of suspender. It makes an evaluation of the influence of suspender laying forms to the vertical and horizontal stiffness of structures and gets the optimal suspender laying forms.
