Dear Scott,

I didn't mean to trash any software. I just said what I was thinking. However, I'm thankful to you for your patience, and changing my mind!

Regards

Dear Scott, First of all, I should say I believe in your keen knowledge in opensees and also in structural engineering. The reason that I continue this discussion is only to debate on whether opensees has such capabilities or not. And I really appreciate your effort. Anyway, what I mean by the "whol...

Dear Scott, I cannot understand what you mean by "it makes no sense ..."! Imagine we have a 2D frame and we want to perform a nonlinear dynamic analysis on it. I want the behavior of THE WHOLE STRUCTURE to be like Clough's model, while you might want it to behave as Takeda's model. Definitely, there...

Unfortunately Opensees doesn't consider any hysteresis model. here is the link that proves my saying: http://opensees.berkeley.edu/community/viewtopic.php?f=2&t=61028&p=98992&hilit=hysteresis+model#p98992 Although it has been viewed for more than 200 times, nobody (even software developers!) has giv...

Hello,
I couldn't find any download link for "OSP" and "TCL Editor" in opensees website! could anyone tell me please where may I find them to download?
thanks.

Hi, Is there any convergence problem when using force-based elements in opensees? while I was reading "opensees command language manual" which has been printed on 1 July 2007, I encountered this notation: "NOTE: the forceBeamColumn (nonlinearBeamColumn (page 218)) element might have problems converg...

Dear prof Scott,
Thanks for your answer to my questions. of course you are right. I just wanted to know if there is other ways or options in opensees (instead of defining several nodes and using more elements) to perform mesh refinement, and I wonder if you could tell me if there is!
Regards

Thanks a lot dear wuhaoshrek

Hi, As far as I know, we can improve the accuracy of solution for FBE by increasing the NIPs, while in DBE this goal can not be achieved in a same way. And it is recommended that if you want to enrich the response, you should use "mesh refinement" in DBE. Could you tell me plz how can we refine the ...

It seems this discussion is going to be the most informative topic debating on plastic hinges in opensees! thank you professor vesna ...

Hi, Is it true that FBE cannot contribute the mass assigned to it toward a time history analysis?! I heard it from someone who said that although DBE has the ability to involve its mass (the mass you have assigned to it using "element mass") during analyses, FBE does not have the same power, and if ...

Thanks a lot for your help. When i open filename.xml in a web browser (such as IE), the data is not in column format, therefore difficult to analyze outcomes further. Could you tell me please how can I solve this problem? It should be noted that when I open the file with notepad, I do not encounter ...

Dear all, I use < -xml > instead of < -file > to record outputs because I want to figure out each column's label. My problem is that when I run the model and the output is made, the file can be open as a text file in notepad by default, and therefore nothing is clear! I want to ask that when I use <...
