摘要
吉林龙华松花江特大桥抗震设计方案中拟使用近年来新出现的lock up装置和液体黏滞阻尼器.建立了大跨度桥梁使用lock up装置和液体黏滞阻尼器在桥梁地震反应中的分析模型及方程,采用动态时程分析法,对龙华松花江特大桥在多点一致激励作用下的地震反应进行了分析,探讨了使用新型地震结构保护装置对大跨度连续箱梁桥地震响应的影响.
With the development of earthquake protective system, the anti-seismic ability of long span bridge could be enhanced. In anti-seismic ability design, Longhua Songhua river bridge in JiLin province will use lock-up devoice and fluid viscous damper that appears in recent years. This paper sets up the model and equation of long span bridge using lock-up devoice and fluid viscous damper in multi-supported excitation's seismic analysis. With the dynamic time history analysis, it makes Longhua Songhua river bridge's seismic response analysis and discusses the influence to long span continuous box-girder bridge with using new earthquake protective system.
