Beam Attributes: Global Point Moment

Description

Assigns point moments to selected beam elements using three orthogonal components and a coordinate system.

The moment may be positioned at any point along the beam.

Point moment attributes are load case dependent.

Dialog

Moment X / Y / Z

Three orthogonal components of moment vector.

a

Position of the force along the beam expressed as a ratio of the beam's length. The distance is measured from end 1 of the element, with a=0.0 corresponding to end 1, and a=1.0 corresponding to end 2.

ID

Assigns an ID to the attribute.

By using different IDs, multiple moments can be applied to the same element for the same load case.

IDs are positive integers between 1 and 192.

Coordinate System

The coordinate system (UCS) in which the moment components are defined.

The UCS is used only to define the global Cartesian components of the moment. Subsequent changes to the UCS do not affect the direction or magnitude of the moment.
