A Research of Mechanic Characteristics on the Continuous Flange-Linked Binal Box-Girder Bridge

A continuous beam bridge has a 36.0 m wide deck with two box-girders whose flange is linked instead of crossbeam.Mechanic characteristics is analyzed on the bridges by building spatial models.Compared with seperated pair of box girder,the flange-linked bridge integrity is in good condition and its deflection is decreased obviously because of the increased lateral restraint,which was proved by theoretical analysis and bridge test.
