Web crippling and combined bending and web crippling of cold-formed steel beam headers

Experimental and numerical investigations on the bending capacity of cold-formed steel box headers

“…Lastly, web crippling arises due to stress concentration in the case of built-up box shapes under interior-one-flange loading. The combined crippling strength and bending strength exceed the summation of two independent C-sections 27 .…”

Web crippling behaviour of laterally restrained cold-formed steel re-entrant profiled deckings

“…There is a concern on the general applicability of these empirical design rules as reported by Stephens and LaBoube [5] and Zhou and Young [6] as new sections and profiled deckings with different steel grades and geometries are being developed all the times. Furthermore, it is argued that there are only limited advantages in developing such design rules for web crippling resistances of profiled deckings at all as web crippling tests are simple tests to be carried out, and they will have been carried out anyway during product development in order to attain high structural efficiency as well as market competitiveness.…”

Aluminum tubular sections subjected to web crippling

“…An experimental study was conducted by Stephens and Laboube [1] to establish the web crippling strength of both box and I-beam headers for an interior-one-flange (IOF) loading condition. Based on the results of this study, design recommendations were proposed.…”
