“…Although Marsh et al [32] found that the diagonal compression at the tension corners of the web increased after buckling, they still concluded that flanges contribute to the shear capacity of panels due to their bending strength, which permits the development of some diagonal tension.…”

“…It is a fascinating historical irony to formulate a buckling problem in terms of tension, but one rooted in compelling experimental observations. However, the assumption that compressive stresses do not increase in the postbuckling range was shown not to be accurate based on findings from numerous authors using finite element (FE) analysis [2,3,8,9,10,11]. In fact, near the edges, compressive stresses increase considerably [3].…”

Tension field theory has traditionally been used to determine the ultimate postbuckling shear strength of steel plates. More than a dozen theories have been proposed in the last nine decades to describe and predict this phenomenon, and all are based on the tensile response of the web plate, referred to as tension field action. Alternatively, in this paper a compression approach for determining the ultimate postbuckling shear strength is studied. First, an experimentally-validated finite element model is used to examine the mechanics of plate shear buckling. The response is shown to be similar to axially compressed plates, but in this case the axial compression is acting on a diagonal. Then a physical model and formulation based on the compressive strength of the plate is developed for predicting the ultimate postbuckling shear strength of a plate. For common design parameters of most bridge and building structures, this compression approach produces strengths that are closer to experimental and finite element results than the best and commonly accepted formulation based on tension field action. Overall, the results of this study show that a compression approach to predicting the postbuckling shear capacity of plates is an honest representation of shear buckling mechanics and has good correlation to extensive experimental results, where in many cases improved correlation is seen compared to formulations based on tension field action.
