摘要
桥梁作为交通生命线的枢纽工程,是交通基础设施震后功能恢复的关键所在。摇摆结构可将地震损伤控制在摇摆界面以避免主体结构破坏,且具有较好的抗震性能和自复位能力,因此在提高结构震后恢复能力方面具有显著优势。首先简要介绍摇摆桥墩的基本原理,回顾了摇摆理念在桥梁工程应用的发展历史,综述了摇摆桥墩的研发和试验研究、摇摆桥墩与上部结构的连接方式、摇摆结构分析方法等发展现状,总结了目前摇摆桥墩研究的不足和发展趋势。
As important joints of transportation lifeline systems,bridges have a significant effect on the resilience of post-earthquake serviceability.Rocking structures can limit damage in rocking interface to void damage in main structure,with fine seismic performance and self -centering capacity.Therefore,rocking structures have significant advantages in improving post -earthquake resilience.This paper introduced the basic mechanism of rocking piers and its application history briefly,and then reviewed the state of the art of rocking pier development and experiment,joint construction of rocking piers and superstructures,and analytical method of rocking structures.The shortages and development tendencies of existing rocking piers were summarized.
