| 摘 要： | 本文根据某自锚式悬索桥独特的动力特性,分别提出了在悬索桥主梁与主塔之间沿纵向设置粘滞阻尼器和铅挤压阻尼器的消能减震设计方案,来控制悬索桥的纵向地震反应。研究表明,采用以上2种消能减震技术,可以有效地减小悬索桥的纵向地震反应。本文研究结果可供工程实践参考。

| Abstract: | Based on the particular dynamic characteristic of self-anchored suspension bridge,a designing scheme was proposed to install the viscous dampers or the lead extrusion dampers between the deck and the main tower to improve the longitudinal seismic response of the bridge structure.Analysis shows that the longitudinal seismic response of the bridge can be reduced effectively by the application of the above technique,which may be used as a reference to engineering practice. |
