Line loads for pier caps can be applied based on the definitions made using the parameters below.

Pier Cap Load

Pier Cap: Choose the pier cap to impose the line load.

Stage: Select a stage to apply the load.

Start Normalized Distance From Right (relative0-1): The relative distance where the line load starts to be appliedmust 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 along the alignment direction, looking upstation (to the right in the standard view).

End Normalized Distance From Right (relative0-1): The relative distance where the line load ends to be applied.

Fx [kip]: Force in X direction. The longitudinal direction along the alignment will correspond to the X direction.

Fy [kip]: Force in Y direction. The transverse direction along the alignment will correspond to the X direction.

Fz [kip]: 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 [kip-ft]:

My [kip-ft]:

Mz [kip-ft]: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 along the alignment direction, looking upstation (to the right in the standard view).

Fx: Force in the X direction with respect to the global coordinate system.

Fy: Force in the Y direction with respect to the global coordinate system.

Fz (Gravity): Force in the Z direction with respect to the global coordinate system.

Mx: Moment in the global X-axis direction.

My: Moment in the global Y-axis direction.

Mz: Moment in the global Z vertical direction.
