A release is defined by six components of force along a linear structural element such as columns, beams, and braces.
- Fx - axial force (X direction)
- Fy - shear force (Y direction)
- Fz - shear force (Z direction)
- Mx - torsion force (X direction)
- My - bending moment (Y direction)
- Mz - bending moment (Z direction)
Release conditions are Fixed, Pinned, Bending Moment, or User-defined. The default value for analytical columns is Fixed. The default value for analytical beams and braces is Pinned at both ends.
- Pinned Release Condition is defined as all moments released.
- Fixed Release Condition is defined as no releases.
- Bending Moment Release Condition is defined as my and mz released (torsion not released).
- User-defined Release Condition is defined as all releases made available for engineer to define as needed.
