I want to place an eccentric distributed load on a beam in Risa 3D in order to induce torsion in the beam. It doesn't seem that Risa 3D accommodates this. Can anyone confirm? Thanks!
Go into the Distributed Load window. Under the second column (which is labeled "direction") select [red]Mx[/red] as the direction. This is the torque applied along the beam.
Read the help menu under "Distributed Loads Spreadsheet".
