Longitudinal vibration joint control restraint system and method for large-span suspension bridge
The invention discloses a longitudinal vibration joint control restraint system and method for a large-span suspension bridge. The system comprises the suspension bridge, a temperature self-adaptive damper module and a limiting blocking module, wherein the temperature self-adaptive damper module and the limiting blocking module are arranged on the suspension bridge. The temperature self-adaptive damper module comprises a plurality of temperature self-adaptive spring dampers which are arranged between lower cross beams and main beams of the two bridge towers in the longitudinal bridge direction; the limiting and blocking module comprises a plurality of longitudinal limiting stop blocks which are arranged between the lower cross beams and the main beams of the two bridge towers in the longitudinal bridge direction; the dampers generate different constraining forces under the low-speed action caused by temperature changes, the medium-speed action of automobiles or fluctuating wind and the rapid working condition caused by earthquakes respectively, and the longitudinal limiting check blocks generate the constraining force which ultimately limits longitudinal relative large deformation between the bridge tower and the main beam under the working condition of the most unfavorable load combination. The longitudinal vibration joint control constraint of the large-span suspension bridge is realized through the four constraint forces; vibration and vibration combined control of the large-span suspension bridge under different speed working conditions can be met.
本发明公开了一种大跨径悬索桥纵向振震联控约束系统及方法，系统包括悬索桥和设于悬索桥上的温度自适应阻尼器模块和限位阻挡模块；温度自适应阻尼器模块包括沿纵桥向设于两个桥塔的下横梁与主梁之间的若干温度自适应弹簧阻尼器；限位阻挡模块包括沿纵桥向设于两个桥塔下横梁与主梁之间的若干纵向限位挡块；阻尼器在温度变化引起的低速作用、在汽车或脉动风的中速作用以及地震引起的快速工况下分别产生不同的约束力，纵向限位挡块在最不利荷载组合工况下产生最终限制桥塔和主梁之间的纵向相对大变形的约束力；通过四个约束力共同实现大跨径悬索桥的纵向振震联控约束；能够满足大跨径悬索桥在不同速度工况下的振动与震动联合控制。
