WebJul 30, 2011 · Tension Flange Yielding (TFY) Sections that are unsymmetrical about the axis of bending and sections with slender webs may be controlled by yielding of the tension flange. For this case, the limiting moment is the one that causes stage 2 shown in Figure 8.2.1.1. This limit state will usually only become an issue for built up plate girders. Weballowable stresses are determined, and the effect of lower flange bending is also addressed by two different approaches.
