T-Section Geometry

b_f — effective flange widthmm

b_w — web widthmm

t — flange / slab thicknessmm

How do I find b_f? (NSCP Table 6.3.2.1)

Effective flange width is your input — work it out first, then type the governing (smallest) value.
Interior T-beam, b_f ≤ least of: b_w + 16t · centre-to-centre spacing S · b_w + L_n/4.
Edge / inverted-L (one overhang): b_w + 6t · b_w + S_w/2 · b_w + L_n/12.
