The Influence of Shear Effects on the Deflections of Steel Box Girder Bridges

open access: greenActa Polytechnica, 2000
It is already well known that the shear lag phenomenon, generated by shear deformations in the flanges of box girders, can result in a very non-uniform distribution, across the flange width, of longitudinal normal stresses, and consequently can then ...
