Lateral buckling of continuous composite bridge girder
Original language description
Composite bridges consisting of several parallel bridge plate girders connected to a concrete deck are favourably used for middle spans. If the structure is continuous over several supports one of the main design tasks is to ensure stability. Lateral buckling may occur in the regions close to internal support where the compressed lower flange does not get any continuous lateral restraint. The tensile upper flange is restrained continuously in lateral displacement (rigidly) and rotation (flexibly). The steel part of deep bridge girders usually distorts while buckling and so called lateral distortional buckling (LDB) appears. The theory for lateral buckling of thin-walled cross-sections cannot be applied in case of LDB because of the cross-sectional distortion. In common practice the problem is solved by the method of inverted continuous U-frame. Recently the more precise solutions have been searched by using finite elements and finite strip methods. At the moment a parametrical study is
