Using OpenSees!
Dear all,
I am considering using OpenSees software in plane strain SSI analysis
under cyclic loading. I have understood, roughly, how the structure of
the input file and the Tcl scripting language work. Nevertheless, I
would like to know; I understand that to model a rigid body, in
OpenSees, you can tie the horizontal and vertical displacements of the
nodes of the rigid entity. Is there any other way? Or did I
misunderstood?
