2D Face Loads

Face loads can be constant or varying across the face of an element. For a point load on the face the load vector is

This can be generalised for the distributed case giving the load vector as

where integration is over the surface of the element. Using Gaussian integration this can be expressed as

Where are the Gaussian weights and is the determinant of the Jacobian.

Note: In GSA, loads can be applied to a list of members or elements. Any loads applied onto members will be automatically expanded into the appropriate elements loads in the solver in order to analyse the model.
