# Beam Loads
The reference mechanical load is the point load; all the other mechanical load types can be established by integrating the results for a point load over the loaded part of the beam.
The basic approach to calculating the load on the beam for a force at
There must be continuity of displacement and rotation between the two
beams and the forces and moment must balance the applied load. This
allows a set of equations to be set up for the sub-beams
Where the vector
Once the force and moment at the loaded point have been established the end forces and moments (and hence the equivalent nodal forces) result from equilibrium of the two sub-beams.
The general distributed loading in the patch load, varying in linearly
in intensity from position
The tri-linear load option is simply a repeated set of patch loads.
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.
