【摘要】 近年来,纤维增强复合材料(FRP)已经在人行天桥中得到大量应用,但是超高车辆撞击是其安全的重要威胁。为研究超高车辆撞击FRP人行桥的破坏机理,本文开展了超高罐车撞击FRP人行桥的模型实验研究。确定了此类梁的撞击破坏过程,位移响应和损坏机理,为改进FRP人行桥防撞性能提供参考。更多还原

【Abstract】 In recent years,Fiber Reinforced Polymer(FRP) has been widely used in footbridges.However,the collision of over-height truck is a serious threat to these bridges.In order to study the damage mechanism of the collision between over-height trucks and FRP footbridges,a model test for the collision between a FRP pultruded box-girder and an over-height tank truck is implemented in this work.The collision process,displacement response,and failure mechanism are obtained,which could be used for the future optimum collision-prevention de sign of FRP footbridges.更多还原
