无索区长度对桥梁受力性能的影响显著,适宜的无索区长度能够优化桥梁整体结构的受力,因此长度的选取在桥梁设计中尤为重要。本文以湘西某跨径为(196+101+62)m的独塔斜拉桥为工程背景,利用有限元分析软件Midas civ...展开更多 无索区长度对桥梁受力性能的影响显著,适宜的无索区长度能够优化桥梁整体结构的受力,因此长度的选取在桥梁设计中尤为重要。本文以湘西某跨径为(196+101+62)m的独塔斜拉桥为工程背景,利用有限元分析软件Midas civil建立分析模型,对塔根处和梁端处的无索区长度进行单因素分析。结果表明:塔根处及梁端处无索区长度的变化对主跨主梁挠度,边跨主梁挠度等影响显著,而对斜拉索最...
