Hi, Seeing that in these messages you are talking about constraints, I would like to ask which constraint command can be better for replacing the usual 'Plain' if I have in my model a few rigid links between beams, created only because I have a column with different sections not symmetric, so the x-...

Hi, Obviously I'm not the right person that has to answer to your question because I'm still a beginner in using OpenSees, but I created a new Concrete material for my graduation thesis. The way I used for working with it like another material has been to download the last version of the source code...

Hi everybody, I put my message here only to don't create another topic. My question is about the implementation of this material in OpenSees. In this page.. www.uwm.edu/~jzhao/Bond_SP01_pages/Bond_index.html ..there is written by the material's authors that they have fixed a mistake in the original ...

Hi I have a question about geometric transform for rotating local coordinates.. First I want to ask if it can be a correct choice if I have to do a pushover analysis in a direction different from global axis (in my case 45° on plane yz), so to use this new coordinate system for definig the pushover ...

I have a question abuot the Recorders in a fiber section. I modeled a section reinforced concrete section with confined and unconfined concrete, and I've written in the script to record the stress-strain responce in some points of the section. I got no problems for the steel bars, but the recorders ...
