摘要
以某特大悬索桥为例,通过建立有限元模型进行数值计算,定性地分析了几何非线性因素对桥梁结构风致抖振响应的影响。
Based on one extra large suspension bridge, the influence of geometrical nonlinearity factor on bridge structure wind - induced buffeting response has been qualitatively analyzed by establishing finite element model for numerical calculation.
