You're absolutely right. One gets so used to using beam-type elements that sometimes other element options slip our minds. Thanks so much!

Hello everyone, I just tried version 3.7 of OpenSees to create a simple single-degree-of-freedom model, where I added a stiffness-based damping model and applied a pulse-type load. It seems the Rayleigh function isn’t correctly incorporating the value of beta_K, as the displacement history does not ...

Is there any recorder to obtain energies dissipated in the model such as plastic energy, input energy, damping energy, etc? It'd be very useful for energy based seismic design of structures.

Thanks again!

Hi, I'm trying to obtain in a concentrated plasticity model the damping forces aiming at obtaining the damping energy by integration of damping forces and nodal displacements. I've used the model for damping "modalDamping" and the recorders "rayleighForces" and "rayleighForc...

Hi guys, Would it be possible to finish one analysis and then use these results as a starting point to begin the next analysis? I guess that it would be possible to begin a new analysis imposing the permanent displacement from the previous analysis, but what I really want is to start the new analysi...

Finally, I found a forum where apparently it is explained.

If I'm right, it is not possible to perform buckling analysis in OpenSees. Is there any intention to update the software in this sense?

Regards,
David

If you get a solution, please post it

Not yet. We will wait for a solution

Do you have the same problem?

Hello everyone, I tried to install StarCluster on Windows for running my models on AWS cloud. I follow successful the steps until I reach the following step: "Once you’ve installed the above dependencies into your Python 2.7 installation you can now run: c:\> easy_install StarCluster" When...

I have the same problem. Did you fix the problem,TPdct?
Could anyone write a tipical values for H and delta parameters for steel or aluminium?

Thanks guys!

Yes, it is You must use system FullGeneral and after your analysis, you must add the following: set controlTime [getTime]; set ok [analyze 1 $dtcal]; <----------Your analysis set Kfile [join [concat "K" "$controlTime" ".out"] "" ] printA -file $Kfile;

Thanks Silimgunay!
And what about Force vector?, is there any implemented function to obtain it? like printA for K and M

Thanks!

Hello, I would like to know how many steps the ground motion has, when I use the script bellow. I mean, I have a file with the ground motion acceleratons but when I introduce it to OpenSees by "set AccelSeries " Series -dt $dt -filePath $outFile -factor $GMfatt" " I would like to...
