摘要
以某主跨110m的自锚式钢管混凝土中承桁架拱桥为对象,分析了该桥的自由振动特性和车辆荷载作用下主跨桥面系振动的特性,并依据人行桥的舒适度指标评价了振动的舒适性。
Taking a self-anchored half-through concrete filled steel tubular truss arch bridge with a 110 meters main span for example, the natural vibration properties and vibration properties of main span deck system under moving vehicle load were analyzed, and the dynamic comfort was evaluated according to the indicators of pedestrian bridges.
