摘要
拱桥是中等跨度桥梁结构的首选桥型之一,钢管混凝土拱桥在我国得到了广泛的应用。以湖南益阳茅草街林桥为例,研究了中承式钢管混凝土系杆拱桥的动力特性及其影响因素,研究表明,中承式钢管混凝土系杆拱桥横桥向刚度较小,而增加横撑可以有效提高其横桥向刚度和动力稳定性。
Arch bridge is one of candidates of moderate-span bridges.Arch bridges have been extensively applied in China.Finite element model is established for Hunan Yiyang Maocaojie Arch Bridge.The modal analysis of this bridge is carried out.The impact of some parameters on the modal properties is also studied.The results indicate that the bridge is readily vibrated along transverse direction.The effect of traveling wave on the moment of the arch is large.
