Description

This video illustrates out-of-plane distortion cracking at a transverse stiffener detail in the laboratory. The applied displacements shown are much greater than would be expected in an actual bridge; however, the cracking is identical to what would be found in an actual bridge. Note that cracks initiated and grew at both the stiffener-to-web weld and the web-to-flange weld.
