Concentrated nodal mass (principal moments of inertia with angles)

Definition of mass moments of inertia by specification of the principal moments of inertia and the respective angles describing the corresponding axes of principal moments.

Note: For detailed load explanation see also RM Bridge Load Types Library .

Note: Loads of this type do not apply to static calculations.

Setting	Description
From, To, Step	Node series, where the mass moments of inertia are applied
gImx, gImy, g*Imz	Principal moments of inertia (multiplied by g)
Beta, Alpha1, Alpha2 (Deg)	Angles for describing the inertia axes (same convention than for the local coordinate system of beam elements)
