Girder Load

Girder loads can be defined based on the selected girder, construction stage, applied flange, and magnitudes in terms of forces and moments.

Girder: Select the girder to which the load will be applied.

Stage: Choose the stage at which to apply the load.

Applied Flange [Top/Bottom]: Specify the flange as either the top or bottom using this parameter.

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.
