Surface Load [CUG]

General

Surface: The user must choose either an arbitrary polygon or quadrilateral definition 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]: OpenBrIM distributes the defined surface loads to the chosen element nodes as nodal loads based on their respective tributary area. OpenBrIM automatically computes the tributary area of each node.
