摘要
在忽略桥面结构的主梁与拱肋刚接点的转动对吊杆力的影响的情况下,推导出组合拱桥的吊杆拉力的简化计算方法,揭示这种结构体系的力学本质,也有助于设计者进行合理的概念设计。
When neglected effects which grider of deck structure and rotation of rigid joint of arch ribs work,suspender tension and simplified method for tension calculation of suspenders of composite arch bridge are deduced.At the same time,mechanical essence of this structure system is revealed,which is helpful to concept design for designers.
