摘要
采用桥梁结构三维非线性空气静力分析方法,考察静风的不同初始攻角对结构静风稳定的影响,利用等截面即介于等刚度和等强度之间的原则对CFRP索与钢缆索结构大跨度悬索桥在静风荷载作用下的变形特征和稳定性进行分析和比较。
this paper, three-dimensional nonlinear static analysis of the air bridge structure method, cross-sectional study the effects of different initial static wind attack angle of the wind on the structure of static stability, and utilization of principles that ranged between stiffness and strength of the CFRP and other long-span suspension bridge cable deformation characteristics and stability of the steel cable structure under wind loads were analyzed and compared.
