Girder and Stage
Girder: Specify the modeled girder to which the defined loads will be applied.
Stage: Specify the stage at which the loads will be applied to the girder.
Girder Line Load
Applied Flange [Left/Right/Both]: The flange at which the defined loads will be applied throughout the girder can be specified 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 direction (gravity direction). For typical loads (such as wearing surface loads or 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.
Girder Point Load
In the case of applying point loads to a girder object, this section of the girder load can be used.
Reference Location [Start/End/Middle]: The reference location for the point load (start, end, or middle) can be specified using this parameter.
Offset from Reference Location: This parameter allows you to offset the point load from the reference location. A positive offset value will move the point load in the upstation direction, while a negative offset will move the point load in the downstation direction.
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 direction (gravity direction). For typical loads (such as wearing surface loads or 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.
