新西兰可控摇摆提离高墩桥梁设计建造综述
A review of design and construction of controlled rocking uplift high-pier bridges in New Zealand:a case study of the South Rangitikei Railway Bridge
摘要
Abstract
Controlled rocking uplift bridges represent a pivotal advancement in seismic-resilient structural design.Utilizing dual-column high piers that undergo alternate lifting/settling trans-versely,this bridge induces controlled lateral rocking uplift to mitigate seismic forces transmitted to slender reinforced concrete piers.Energy-dissipating dampers at the pier base rocking interfaces can further restrict uplift displacement and abutment movement.In this review,we first intro-duce the fundamental concepts of self-centering rocking bridge structures.We then systematically detail the design idea,structural connections,experimental validation,and dynamic behavior of the South Rangitikei Rail Bridge using the controlled rocking uplift technology and summarize construction methodologies for critical components(pylon caissons,piers,and box girders).Finally,the application prospects of typical controlled rocking uplift tall-pier bridges are evalua-ted.The results demonstrate that(1)rocking structures exhibit amplitude-dependent natural periods and nonstationary vibration frequencies,precluding conventional modal decomposition;(2)uplift-capable piers enhance seismic stability through pronounced hysteretic damping during rocking and uplifting;and(3)impact mechanisms at uplift interfaces,combined with supplemen-tal damping devices,effectively suppress seismic responses,minimize residual displacements,and strengthen self-centering capacity.This study provides valuable insights for designing resili-ent bridges in high-seismicity regions of China.关键词
