| 摘 要： | 近年来,纤维增强复合材料(FRP)已经在桥梁工程中获得了逐步推广和应用,尤其是在人行天桥的设计和建设中。但是,超高车辆撞击城市桥梁上部结构的事故频繁发生,严重威胁城市交通的正常运行。为确保FRP结构能更广泛地应用于城市桥梁中,提高其作为上部结构的抗撞能力,需要深入研究超高车辆-FRP结构碰撞机理。本文基于碰撞试验,对典型的超高车辆-桥梁上部结构碰撞进行了模拟,确定了此类梁的撞击破坏过程,位移响应,作用方式和损坏机理。分析结果将用于有限元分析和验证中,从而改进FRP上部结构应对此类冲击荷载时的结构响应。

| Abstract: | With the increasing expansion in civil engineering in recent years,fiber reinforced polymer(FRP) has been recognized as a competitive material to those conventional materials in bridge structures,especially for footbridge design and construction.However,collision accidents between over-high trucks and bridge superstructures frequently happened,which seriously threaten the safety of bridges and traffic system of city.To ensure FRP structure can be more widely used for bridge construction,FRP structure-vehicl... |
