    Elastic Torsional Buckling of Through Plate Girder Rail Bridges
    Duffield, C ; Hutchinson, G ; Stevens, LK ; Fletcher, G ; Brown, B ; Clifton, C ; Little, J ; Marriott, J ; McIIroy, C (New Zealand Heavy Engineering Research Association, 1986-12-01)
    An investigation has been conducted to study the lateral torsional buckling characteristics of a through plate girder railway bridge at Mitchell River in Victoria. Field measurements of lateral imperfections were taken on a selection of typical bridges. Elastic and non-linear finite element analyses of the bridge model incorporating the field measured imperfections indicated that one critical buckling live load was 6. 5 times the design live load. Possible problems are examined in relation to the vertical stiffeners as a result of this sensitivity to lateral imperfections.
