WebSteel plate girder bridges make use of traditional cross-frame diaphragms to stabilize the compression flange of girders. These braces are required during construction, especially during deck placement, to prevent lateral torsional buckling of bridge girders. WebDiaphragm Abutments The monolithic diaphragm abutment, an integral part of the bridge superstructure extending below the soffit, is connected directly to piles or rests on a footing cap. The roadway embankment is in direct contact with the abutment diaphragm. The major benefits of the diaphragm abutment are its low
