Footing Surface Load [SIG]

Surface loads on footings can be defined using the parameters below.

Footing Load

Footing: Specify the footing to which the load will be applied.

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

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.

Mx: Moment in the longitudinal direction along the PGL.

My: Moment in the direction perpendicular to the PGL.

Mz: Moment in the vertical direction.

Although Fz is applied in the direction of gravity (positive values for Fz will correspond to the downward direction, as with gravity), Mz will have a positive direction relative to the +Z axis or, in other words, in the upward direction.

The Directions of Forces For footings with a rotation parameter defined as a value other than zero, the directions of the applied loads are adjusted accordingly. Refer to the figures provided below for further clarification on the directions of positive forces and moments.
