摘　　要：以一种新型反对称梁拱组合人行桥为例,采用有限元分析理论对该桥型的基频、挠度和应力等进行综合分析,验证该桥型的合理性和实用性。该桥型采用镜像反对称的建筑手法进行布置,结合拱桥与梁桥的特有属性,力求运用自身受力结构展现桥梁景观美学,剔除赘余结构,化繁为简,在保证结构受力安全的前提下,兼顾经济性和景观需求,适合在相关工程中推广应用。Taking a new type of antisymmetric beam arch composite pedestrian bridge as an example,the fundamental frequen-cy,deflection and stress of the bridge type are analyzed comprehensively by using the finite element analysis theory,and the rationality and practicability of the bridge type are verified.This type of bridge adopts the architectural method of mirror image antisymmetry,combines the unique attributes of arch bridge and beam bridge,and strives to highlight the bridge landscape aesthetics by using the stressed structure itself,eliminate redundant structure,and simplify the complexity.On the premise of ensuring the stress safety of the structure,taking into account the economic and landscape needs,it is worth popularizing and applying.
