摘要
以某在建大跨悬索桥为背景,建立了Midas Civil全桥有限元仿真分析模型,分别对不同跨径及猫道选型下的结构受力和安全性结果进行了对比分析。结果表明:分离式猫道会导致桥塔塔顶处受到不平衡水平力作用,导致产生顺桥向位移,且跨径越大,不平衡水平力越大,桥塔的受力和位移响应越大。
With a long-span suspension bridge under construction as the background,the full-bridge finite element simulation analysis model is established using Midas Civil,and the structural stress and safety results under different spans and catwalk selections are compared and analyzed. The results show that the separated catwalk will cause unbalanced horizontal force at the top of the tower,and will result in displacement along the bridge,and the larger the span is,the greater the unbalanced horizontal force,the force and displacement response of the tower will be.
