Sep 06, 2012Web local buckling. If depth over thickness ratio of the web is greater than a certain limit, it can locally buckle or cripple under compression. Web local buckling occurs in a diagonal position and is produced by the diagonal compression existing in the web due to shear. Web crippling occurs due to local compression transferred by the flange to the connecting portions of web.(plate) AA Aluminum Construction Manual(steel) 1.2 Materials.
