建立了刚构体系斜拉桥有限元模型,进行了结构自振特性分析,对设不设置铅芯橡胶支座的2种模型进行了地震响应分析,并对减震支座参数进行了合理性研究。结果表明:刚构体系斜拉桥设置铅芯橡胶支座可以获得良好的减震效果。该结论可供同类型桥梁减震设计参考。
建立瞭剛構體繫斜拉橋有限元模型,進行瞭結構自振特性分析,對設不設置鉛芯橡膠支座的2種模型進行瞭地震響應分析,併對減震支座參數進行瞭閤理性研究。結果錶明:剛構體繫斜拉橋設置鉛芯橡膠支座可以穫得良好的減震效果。該結論可供同類型橋樑減震設計參攷。

The finite element model of rigid-frame system cable stayed bridge was established ,and the structural natural vibration characteristics and seismic response of two models of setting or not setting the lead rubber bearing were ana-lyzed,also the rationality of bearing damping parameters were studied. The results shown that the lead rubber bearing of rigid-frame system cable stayed bridge can obtain good damping effect.
