FRP桥梁上部结构的撞击破坏实验研究
COLLISION TEST OF A FRP BRIDGE BEAM
摘要
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 superstruc tures 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-vehicle collision mechanism should be studied, so as to improve collision-resisted ability of bridge superstructure. In this paper, a collision testing between over-high trucks and bridge superstructure was carried out, including failure process, displacement response, and failure mode and mechanism. The test results will be used for finite element analysis and further verification, so as to improve structural performance of FRP superstructure under such impact load.关键词
