| 摘 要： | 结合两个大跨度悬索桥的工程设计实例,采用反应谱法对其进行了线性地震反应分析,详细讨论了高阶振型对大跨度悬索桥地震反应的影响。分析结果表明:高阶振型对大跨度悬索桥地震反应有很大影响,特别是对主塔的内力反应,而高阶振型对位移反应的影响较小。

| Abstract: | Based on two engineering design case of long-span suspension bridge,the linear seismic response analysis is performed by employing the response spectrum method.The effect of higher frequency models vibration on seismic response analysis of long-span suspension bridge is researched.The results indicate that higher frequency models of vibration have significant influence on seismic response of towers,but have minor influence on displacement response of long-span suspension bridge. |
