Strength of Plate Girder Web Panels under Pure Shear

Strength and Ductility Evaluation Method for Steel Bridge Pier Frames Considering Effect of Shear Failure

“…Because of the strengthening measures of pier-girder joint in steel bridge pier frames, large shear deformation may occur at the mid-span of girder [14]. Similar to the previous research [14][15][16][17][18], the strength and ductility should be considered and verified at the same time. A pushover analysis is terminated when any of the structure's failure criterion is satisfied and this state is taken as the ultimate state of the structure, based on which the ductility capacity of the structure can be determined.…”

Design of intermediate transverse stiffeners for shear web panels

“…Lee and Yoo [32] first found that a laterally supported panel (a panel simply supported at all the edges) is able to develop postbuckling strength quantitatively close to those observed in tests of ordinary plate girders without recourse to any external anchors such as the flanges and adjacent panels. Then, they suggested a simple design formula to predict postbuckling strength through nonlinear finite element analyses of an isolated plate girder model shown in Fig.…”

“…The isolated plate girder model shown in Fig. 6(a), which was used in Lee and Yoo [32], was also used for the determination of the reference shear strength. The web shown in Fig.…”

An analytical approach to modelling shear panels in steel beams at elevated temperatures

“…This indicates that tension field theory should only be used to represent plate girders with transverse stiffeners. Lee and Yoo [19][20][21] carried out a series of finite element studies to investigate the post-buckling behaviour. They modified the existing formulations to decrease the discrepancy between tension field theory and their finite element modelling.…”
