Girder Load [STG]

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 Left Flange/Top Right Flange/ Both Top Flanges/ Bottom Flange]: Specify the flange as either the top left/right or bottom using this parameter. If both flanges are selected, there is no need to increase the load by 2×, since the entered load will already be applied to both the left and right top flanges.

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.

The Directions of Forces See the figures provided below for further clarification on the directions of positive forces. The figures below are taken from the start station of the bridge model.
