Derived section properties

Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For H 346x174x6x9 the computed area agrees with the published value to better than 0.01% and I_x to 0.05%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, Z_x	641,300 mm³
Elastic modulus, Z_y	90,982 mm³
Plastic modulus, Z_px	716,185 mm³
Plastic modulus, Z_py	140,225 mm³
Radius of gyration, rx	145.1 mm
Radius of gyration, ry	38.8 mm

Z is the elastic modulus and Z_p the plastic modulus, following Japanese practice.
