Re: save opensees window
you have to open a file for writhing (the first command in the example), then using "puts" command write lines into a file, and at the end you need to close the open file. All commands for doing this are given in the example.

Re: connection between column and quad elements
you need to tie the column and quad element using equalDOF command, but you need to tie them only in 2 DOFs.

Re: Why do I get this error with ViscousDamper material
Are you using the latest version of OpenSees? This is a new material so you need to use the latest version of OpenSees for it to work.

Re: shear computation in nonlinearBeamColumn Element
Can you post a simple example with only one element that demonstrates your problem?

Re: Problem with moment curvature analysis
from what you have described it looks like you have an error in your fiber section. Here you can find an example of a rectangular hollow section:http://opensees.berkeley.edu/wiki/index ... on_Example

Re: geometric transform problem
it looks to me that in your model you have force-based element of zero length.

Re: double section
when defining the section set the local coordinate system at the centroid of the section and define the rest of the section relative to these coordinates. you can find many examples on how to build a fiber section here: http://opensees.berkeley.edu/wiki/index.php/Examples_Manual#Section_Modeling_And...

Re: CBF buckling bracing
i think that you can use the basic principals proposed in that report to model X braces. just make sure to define the connection between two braces properly.

Re: save opensees window
use "puts" command to write those lines into a file.
On page 8 of this file you will find an example on how to manipulate with the files:

Re: How to model axial-flexural hinges in opensees
I believe that such code exists but unfortunately it is not documented. Look for it at the source code.

Re: drift response
I think that with the "remove element" command you can remove only one element. to remove all segments of the brace you will have to issue several remove element commands. if you do it within a loop it may not be that difficult.

Re: s-dof system
you can use zeroLength element to model the spring (http://opensees.berkeley.edu/wiki/index ... th_Element) and Rayleigh command (http://opensees.berkeley.edu/wiki/index ... ng_Command) to assign damping to it.
