Point loads on pier caps can be applied at the specified stage once the related definitions are made by specifying the parameters below.
Pier Cap Load
Pier Cap: Choose the pier cap to impose the nodal load.
Stage: Select a stage to apply the load.
Normalized Distance From Right (0-1): The relative distance where the load is applied must be specified with a value between 0 and 1, where 0 corresponds to the initial node of the selected pier cap and 1 corresponds to the final node. The initial node is defined in the direction of alignment, looking upstation (to the right in the standard view).
Fx: Force in X direction. The longitudinal direction along the alignment will correspond to the X axis direction.
Fy: Force in Y direction. The transverse direction along the alignment will correspond to the Y aixs direction.
Fz (Gravity): Force in Z direction. A positive value will apply the load in the gravity direction, while a negative value will apply the load in the opposite direction.
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 and moments.
