南京江心洲大桥是一座独塔自锚式悬索桥,采用弹塑性阻尼支座实现滞回耗能作用,大大改善了桥梁结构的抗震性能,大桥支撑体系结合桥梁运营和抗震的需求进行设计,各处支座首先满足竖向支反力的要求,再根据抗震需要设置阻尼器。
Nanjing Jiangxinzhou Bridge is a single-tower self-anchored suspension bridge, which uses elastic-plastic damping support to achieve the effect of hysteresis energy dissipation and greatly improves the seismic performance of the bridge structure. The bridge support system is designed according to the requirements of bridge operation and earthquake resistance. Block first meet the requirements of vertical support, and then set the damper according to the seismic needs.
