Abstract

Recently, several researchers have attempted to use CFT as a girder of the bridge system. By applying CFT to the girder bridge system, noise and vibration induced by cars or trains, which is the major disadvantage of the steel I-girder bridge, can be reduced and significant increase in flexural strength of the system is expected. In this study, flexural strength of the CFT girder bridge system was investigated by analytical and experimental research. Based on plastic-stress distribution method, simple equation to evaluate the flexural strength of the CFT girder bridge system was derived. The suggested equations were then verified by comparing with the results of non-linear finite element analysis and test.
