steel plate shear wall modeling

[afsoon]

hi all
I want to model stell plate shear wall in a 2D frame.but I have a problems in "block2D" command.I want to know: can I use block2D command with ShellMITC element type in 2D frame? the block2D command don't accept my coordinates.what is the problem?????
please help me couse I don't know so much about opensees in such modelings

no. use tcl scripting to build the shell elements.

[afsoon]

thanks but shell elements also need 3d frame.

[fmk]

you can mix 3dof and 6dof models if you want .. create the shells using the 6dof model and tie the 3dof and 6dof nodes together using the equalDOF command

[afsoon]

thank you.I will try it.
one question: with which command I can connect 2 nodes with same coordinates that one is end of pinned element and another is rigid node( I want it to have rigid behaviour) ?

[fmk]

equalDOF

[afsoon]

thanks but as I tried equalDOF makes 2 nodes behave as a hing ( such 1 node 1 hing) I am so confused....

go talk to your advisor.
