Flange crippling
Webto as interior two flange loading, shown in Fig. la, and if at the exterior edge then it is referred to as exterior two flange loading, shown in Fig. lb. The primary mode of failure of two flange loaded deck sections is web crippling, where the ultimate load carrying capacity is a function of a number of para Webcrippling also can occur either with point loading on one flange of the member or on both flanges. The following illustrations identify the four possible conditions. General Notes: 1 …
