摘要
文章根据桥梁静风稳定理论,针对600m钢筋混凝土拱桥静风稳定性能问题,运用大型通用有限元软件ANSYS建立计算模型,分析拱桥随风速增加的静风失稳全过程情况,探讨拱桥在静风荷载下的失稳机理。
According to bridge static-wind stability theory, and regarding the static wind stability problem of 600m reinforced concrete arch bridge, this article established the calculation model by using the large general-purpose finite element software ANSYS,analyzed the whole static wind instability process of arch bridge increasing with wind speed,and discussed the instability mechanism of arch bridges under static wind load.
