桥梁减震装置(大吨位阻尼器)的开发应用

通过在桥梁结构的特定部位设置阻尼器,控制结构的动力响应,减轻结构在地震中的反应,是一种行之有效的方法。上海市政工程设计研究院科研所与上海材料研究所共同开发研制的大吨位、大位移耗能阻尼器已成功地应用于重庆长江鹅公岩大桥、上海卢浦大桥、柳州宏光大桥等大型工程,对桥梁结构的抗震减震进行了有益的尝试。

Development and Application of Bridge Damping Device (Large Tonnage Damper)

To install dampers in the specific part of bridge structure for controlling the dynamic response of structure and reducing the response of the structure in the earthquake is an effective measure. The Science and Research Institute of Shanghai Municipal Engineering Design and Research Institute and Shanghai Material Research Institute together research and make the damper with large tonnage and large displacement energy consumption. It has been successfully used in large scale projects such as the Changjiang River Ergongyan Bridge in Chongqing City, Lupu Bridge in Shanghai City, Hongguang Bridge in Liuzhou City etc. It made the beneficial attempt for the anti earthquake and damping of bridge structures.
