2D Body Loads

The most common form of body loads are gravity loads. The general expression for body loads is given by

where integration is over the volume 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.
