  • 高速公路桥梁动力响应统计分析

    车辆行驶引起的桥梁振动的动力响应数据是车桥耦合振动分析中重要参数.采用超声波测速仪、录像机及桥梁动态测试仪同人工记录相结合的方法,对高速公路交通荷载各要素进行24 h连续、全面调查,记录的数据包括车型、车速、行驶车道、车辆到达时间以及每辆过桥车辆引起的桥梁动力响应数据.本调查采集了8片梁的5 650单车过桥的动响应数据,研究了交通荷载调查样本中不同梁体的动力响应数据的统计规律,全面分析了高速公路交通荷载车辆过桥引起的桥梁动力响应的时空分布规律.研究结论能够给车桥耦合振动研究及相关研究提供有益的理论指导和数据支持.

  • Structural Performance of Light Weight Multicellular FRP Composite Bridge Deck Using Finite Element Analysis

    Fiber reinforced polymer (FRP) composite materials having advantages such as higher strength to weight than conventional engineering materials, non-corrosiveness and modularization, which should help engineers to obtain more efficient and cost effective structural materials and systems. Currently, FRP composites are becoming more popular in civil engineering applications. The objectives of this research are to study performance and behavior of light weight multi-cellular FRP composite bridge decks (both module and system levels) under various loading conditions through finite element modeling, and to validate analytical response of FRP composite bridge decks with data from laboratory evaluations. The relative deflection, equivalent flexural rigidity, failure load (mode) and load distribution factors (LDF) based on FE results have been compared with experimental data and discussed in detail. The finite element results showing good correlations with experimental data are presented in this work.
