M10X9

Miscellaneous Beam · AISC Shapes Database v15.0 · United States

M10X9 is a miscellaneous light beam 254.0 mm deep with a 68.3 mm wide flange, weighing 13.4 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.

M-shapes are light I-sections that fall outside the W series — small beams for light framing.

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 M10X9 the computed area agrees with the published value to better than 0.01% and I_x to 0.20%. Where a value is also published, the published one above is the one to quote.

Property	Value
Elastic modulus, S_x	127,561 mm³
Elastic modulus, S_y	8,185 mm³
Plastic modulus, Z_x	150,865 mm³
Plastic modulus, Z_y	13,252 mm³
Radius of gyration, rx	97.3 mm
Radius of gyration, ry	12.8 mm

S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
