在公路交通网中,大跨径悬索桥表现抢眼,却也最易出现问题。由于悬索桥作用重大,因此其设计、施工以及后期的监护和运营维护工作,要求必须非常严格。在设计过程中,桥梁设计师要面对并解决诸多挑战,包括结构的高度非线性、悬索几何线形的优化以及风作用的影响。结构系统的持续变化是进行非线性结构分析的主要原因,对于靠索结构承重的桥梁,必须进行特殊的优化。例如跨
In the road traffic network, the performance of large-span suspension bridge eye-catching, but also the most prone to problems. Due to the great effect of suspension bridge, the design, construction and post-monitoring and operation and maintenance work must be very strict. Bridge designers face and solve many challenges in the design process, including the high degree of non-linearity of the structure, the optimization of the geometry of the cable suspension, and the effect of wind action. The continuous change of the structural system is the main reason for the nonlinear structural analysis. For bridges bearing the load-bearing structure, special optimization must be carried out. For example cross
