Dimensions

h = , tw =

b = , tf =

b1 = b – 2·tw

h1 = h – 2·tf

Area

A = 2·(h·tw + b1·tf) 2

A = h·bh1·b1 2

Centroid

yc = b2

zc = h2

Perimeter

P = 2·(h + b)

Second moments of area

Iy = b·h3b1·h1312 4

Iz = b3·hb13·h112 4

Polar moment of area

Ix = Iy + Iz 4

Radii of gyration

ry =  IyA

rz =  IzA

rx =  IxA
