Beam Section Properties

The following beam cross-section properties are calculated by SpaceClaim and transferred to Ansys.

The area of section:

The X coordinate of the centroid:

The Y coordinate of the centroid:

Moment of inertia about the X axis:

Moment of inertia about the Y axis:

Product of inertia:

The warping constant, shear center and torsional constants are calculated from the warping function. The warping function is the solution to the St. Venant boundary value problem for pure torsion:

Using the Trefftz definition, the shear center and warping constant are calculated purely as a property of the section:

X coordinate of shear center:

Y coordinate of shear center:

Warping constant:
