| 1 | 铰接点纵向间距对铰接跨破坏状态的影响分析显示文摘为了探索铰接位置的纵向间距对桥梁铰接跨破坏状态的影响,本文采用地震工程分析软件OpenSees对美国加州Yuba桥的铰接梁跨建立纤维单元模型,对细化模型和简化模型进行Pushover分析,并且对铰接点两侧主梁的不同纵向间距进行对比研究,结果表明:细化模型能更准确地模拟铰接位置的纵向碰撞;铰接点两侧主梁的纵向间距对结构的碰撞过程、结构的屈服过程有很大的影响;较小的纵向间距有利于延长墩梁固结处主梁的线性工作状态,当此梁段发生屈服破坏时,较小的纵向间距还能有效抑制屈服后主梁刚度下降的速率。 | 孙全胜 吴桐 Walter Yang Reginald DesRoches | 2013 | 土木工程与管理学报2013，30，4： | 4 |

| 3 | Implications of seismic pounding on the longitudinal response of multi-span bridges-an analytical perspective显示文摘Seismic pounding between adjacent frames in multiple-frame bridges and girder ends in multi-span simply supported bridges has been commonly observed in several recent earthquakes. The consequences of pounding include damage to piers, abutments, shear keys, bearings and restrainers, and possible collapse of deck spans. This paper investigates pounding in bridges from an analytical perspective. A simplified nonlinear model of a multiple-frame bridge is developed including the effects of inelastic frame action and nonlinear hinge behavior, to study the seismic response to longitudinal ground motion. Pounding is implemented using the contact force-based Kelvin model, as well as the momentum-based stereomechanical approach, Parameter studies are conducted to determine the effects of frame period ratio, column hysteretic behavior, energy dissipation during impact and near source ground motions on the pounding response of the bridge. The results indicate that pounding is most critical for highly out-of-phase frames and is not significant for frame period ratios greater than 0.7. Impact models without energy dissipation overestimate the displacement and acceleration amplifications due to impact, especially for elastic behavior of the frames. Representation of stiffness degradation in bridge columns is essential in capturing the accurate response of pounding frames subjected to far field ground motion. Finally, it is shown that strength degradation and pounding can result in significant damage to the stiffer frames of the bridge when subjected to large acceleration pulses from near field ground motion records. | Reginald DesRoches Susendar Muthukumar | 2004 | Earthquake Engineering and Engineering Vibration2004，3，1： | 3 |
