Dear all, I conducted a dynamic analysis for a 2D RC frame. I received some error messages (pasted below) for some ground motions, however, the analyses converged successfully. I would like to know whether I can rely on the results or not. Number of Stories in Z: 5; Number of bays in X: 2; Number of...

Dear fmk, I have tried that already with different loops inside as you said too but, it fails ultimately. I have also tried to reduce the step size within the loop for solving convergence as well but it is not working out. However static pushover analysis runs up to 4% drift although with some conve...

Hello everyone, I have been modeling a confined rocking wall which can rotate at its both ends, and also has a post-tensioned tendon at its center. I could successfully run static monotonic and cyclic pushover analysis, however, I am stuck with convergence issue while running non-linear time history...

No, there are no any such non-english character.

Hi, Thank you so much for your great contribution to the OpenSees users. But I would also like to know which version is the latest one. I just downloaded the file which is on the top of your file list and that reads OSLite_V0.193. And as I used it I couldn't see the display of my model. P.S. I need ...

Dear all, I am currently modeling a 2D frame with rocking walls. But I have a problem in cyclic analysis. Following are the information of the elements that I have used in the modeling. rocking wall: dispbeamcolumn and elasticbeamcolumn elements all beams and columns: forcebeamcolumn (tried with dis...

Hi bahrampahlavan, Thanks for the reply. I didn't go with tendon01 material, rather I tried with elasticPPgap material. It works well upto certain drift and there is convergence issue later which I am not able to solve :(. I don't have any idea for how to solve it. Below is the warning message, if y...

hi bahrampahlavan,
Thanks for the answer.
In reponse to your reply, I searched for TendonL01 material, it looks new to me and I am quite unaware about its system. If you could please share a part of your code, it would be helpful for me to understand.

Hi Vesna, I am learning opensees, just the beginners. I am trying to model the hybrid rocking wall with two unbonded post-tensioned tendons. I couldn't find the perfect material to simulate the tendons other than elasticPPGap material in opensees as I need to include only tension behavior in tendons...

Dear mijin,
Can you tell me what kind of material you used for modelling the post-tensioned tendons? My model is showing convergence issues for which I am unknown. Please help me to solve the issues.

Thanks fmk for the reply.
But, I want to use ElasticPPGap just to simulate only tension behaviour as I couldn't find other such material in opensees. And I have kept zero as an initial gap

Hi,

Can you tell me how did you simulate post-tensioned strands in your model? I am also working on the self-centering wall, and using ElasticPPGap material to represent post-tensioned strands shows crash report. I am unaware why it's showing such error. I would be grateful if you could help me out.

How to do displacement control analysis for ElasticPPGap material? It gives some issues in mine

Please, anyone who has a better experience with such post-tensioned tendons. If you can provide me any idea with that of such material where it can account for only tension and cannot take stress when it's in relaxation phase. Your help would be greatly appreciated.
