Line: User must choose the line that was defined beforehand.
Stage: Choose the stage at which to apply the load.
Fx: Force in the longitudinal direction along the PGL.
Fy: Force in the direction perpendicular to the PGL.
Fz (Gravity): Force in the vertical direction. A positive value indicates a load in the global -Z or gravity direction. For usual loads(wearing surface loads - stay-in-place formwork loads), the user should input positive values.
Mx: Moment in the longitudinal direction along the PGL.
My: Moment in the direction perpendicular to the PGL.
Mz: Moment in the vertical direction.
Element[Girder /Deck/Foundation/Pier Cap and Bents]: OpenBrIM distributes the defined line loads to the chosen element nodes.
