Abstract: This paper revisits a fundamental assumption used in most classical failure theories for postbuckled web plates under shear, namely that the compressive stresses that develop in the direction perpendicular to the tension ...

Abstract: Nonlinear analyses have been conducted on three-dimensional finite element models of transversely stiffened plate girder web panels (without longitudinal stiffeners) subjected to pure shear, including the effects of initial ...

Abstract: Numerous works have been presented over the years on the ultimate shear behavior and postbuckling strength of plate girder web panels. Research by Basler has been adopted in AASHTO, and the work by Porter et al. has been ...

Abstract: The bifurcation buckling and the ultimate strength of curved web panels subjected to pure shear are investigated by the finite-element method. To evaluate the ultimate strength of curved web panels subjected to pure shear ...

Abstract: Current AASHTO and AISC specifications require that an intermediate transverse stiffener attached on the shear web panel be designed not only to have a proper bending rigidity to meet the simply supported condition when ...

Abstract: The equation for the required area of the intermediate transverse stiffener stipulated in the current AASHTO and AISC specifications was derived under the assumption that the transverse stiffener is subjected to an axial ...

Abstract: In box girders with wide flanges, an uneven flange stress distribution (the flexural normal stress is greater at the edges than that at the center of the flange), so-called shear lag (or positive shear lag), may occur ...

Abstract: This study revisits the anchoring mechanism believed to be the source of the postbuckling strength of plate girder web panels. In classical tension field theories, it has been implicitly assumed that a tension field cannot ...
