Lead core rubber support and viscous damper combined shock absorption and isolation multi-span continuous beam bridge
The invention discloses a lead core rubber support and viscous damper combined shock absorption and isolation multi-span continuous beam bridge. The multi-span continuous beam bridge comprises a bridge body, bridge piers and a bridge abutment, wherein the bridge body is arranged at the top ends of piers; two ends of the bridge body are respectively arranged on one bridge abutment; a lead core rubber support is arranged between the bridge body and the bridge pier; a viscous damper is arranged at the end part of the bridge body; one end of the viscous damper is connected with the bottom surfaceof the end part of the bridge body; the other end of the viscous damper is connected with the side surface of the bridge abutment; and the viscous damper is arranged along the longitudinal bridge direction. According to the shock absorption and isolation multi-span continuous beam bridge, the lead core rubber support mainly plays a role in shock absorption in the transverse direction of the bridge; the viscous damper mainly plays a role in vibration isolation in the longitudinal direction of the bridge; the lead core rubber support and the viscous damper do not interfere with each other; the purpose of simultaneous vibration reduction in the transverse direction and the longitudinal direction of the multi-span continuous beam bridge is achieved through coordination work of the lead core rubber support and the viscous damper, and the vibration reduction and isolation effect of the multi-span continuous beam bridge is effectively improved.
本发明公开了一种铅芯橡胶支座与粘滞阻尼器联合减隔震多跨连续梁桥，该多跨连续梁桥包括桥梁本体、桥墩和桥台，桥梁本体置于桥墩的顶端，桥梁本体的两端分别置于一个桥台上，桥梁本体和桥墩之间设置有铅芯橡胶支座，桥梁本体的端部安装有粘滞阻尼器，粘滞阻尼器的一端与桥梁本体的端部底面连接，另一端与桥台的侧面连接，且粘滞阻尼器沿纵桥向安装。该减隔震多跨连续梁桥中铅芯橡胶支座主要起到横桥向减震作用，粘滞阻尼器主要起到纵桥向隔振作用，铅芯橡胶支座与粘滞阻尼器之间不发生相互干扰，通过铅芯橡胶支座与粘滞阻尼器的协调工作，达到了多跨连续梁桥横桥向和纵桥向同时减震的目的，有效提高了多跨连续梁桥的减隔震效果。
