Summary

Heated perimeter D for contour and box protection of a steel section; W/D is the weight per unit length divided by D. Based on Milke (2002a), pp. 4-216 to 4-217.

Original vector illustration for Intumescent material, level 2 Intermediate.

Source basis: Milke (2002a), p. 4-216 (W/D and A/P definitions) and p. 4-217 (contour and box profiles; greater W/D, greater inherent fire resistance; less protection material needed)
Alt text: Two sections of an I-shaped steel column: protection following the steel outline and protection as a box, with the heated perimeter marked.
