大跨度悬索桥存在静风失稳的可能。采用APDL语言编制了基于ANSYS软件的大跨度悬索桥非线性静风稳定性分析程序,对大跨度悬索桥的静风稳定性进行了参数分析。分析结果表明矢跨比和主缆安全系数是影响悬索桥静风稳定性的主要因素。
Long-span suspension bridge there may be static wind instability. The nonlinear static wind stability analysis program of long-span suspension bridge based on ANSYS was programmed by using APDL language, and the parameters of static wind stability of long-span suspension bridge were analyzed. The analysis results show that the ratio of span to span and the main cable safety factor are the main factors that affect the stability of the suspension bridge.
