Hi, Sorry, this might be a little non-technical. We are in the middle of getting a workstation for our research group and I wanted to know which computer component to focus more such that OpenSees parallel runs at it's peak speed. Should I focus more on the CPU processor or the RAM? Thanks so much! ...

I don't think you will directly get an output of the Park and Ang damage index. Instead, output the parameters you need, such as displacements and curvatures. Also from the force-displacement hysteresis you can calculate the dissipated hyteretic energy. Finally, you can use these parameters to calcu...

For everyone's reference: I solved my problem using RCSection2d to build the fiber section column element. This section can be updated during the analysis. I wanted to update the reinforcement area of the top layer to model corrosion deterioration. After defining my section and element as: set RCSec...

Thanks, Frank. If I understand correctly, I should recompile OpenSees after modifying the code and adding the setParameter() and updateParameter() methods. Should I be modifying the cpp code for only the "layer" command then? I will follow the cpp files for RCSection2d (which I believe can...

Hi, I have a fiber section column model (from the OpenSees examples) in which I want to change the reinforcement area in between a ground motion time history analysis. The part of the code I am trying to modify is: " section fiberSec $ColSecTag {; # Define the fiber section patch quadr $IDconcU...

Thanks, Frank. That helped. For everyone's reference: In the pushover file, you just need to replace pattern Plain 200 Linear {; # define load pattern -- generalized load 2 $Hload 0.0 0.0 0.0 0.0 0.0 } with pattern Plain 200 Linear {; # define load pattern -- generalized load 2 $Hload 0.0 0.0 } It w...

Hi! I am trying to do the pushover analysis using the fiber section from the OpenSees examples here: http://opensees.berkeley.edu/wiki/index.php/OpenSees_Example_3._Cantilever_Column_with_units Every time, it shows the error: " Node::addunbalLoad - load to add of incorrect size 6 should be 3&qu...

Hi Andrette, glad to see this post and thanks for posting your code. Could you please tell me where can i get the experimental data for this test? Thanks!

Hello, In my OpenSees analysis I want to update the material during the analysis and I trying to figure out how to do so. A simple example would clarify, as follows: I have a reinforced concrete column subjected to an earthquake pulse load. Let the total duration of the pulse be t. What I intend to ...
