WebFeb 22, 2024 · Web crippling phenomenon is observed in cold-formed members as the webs are usually thin and unstiffened. Web crippling may develop under different loading conditions; defined based on the application of load applied on one-flange or two-flanges as shown in Fig. 1 as per AISI-S909 ( 2008 ). Fig. 1 WebWeb crippling is the buckling of the web due to the compressive force delivered through the flange. So, the concentrated load should be transferred from flanges to the web on sufficiently large bearing areas.
