Good Afternoon, I need the source code of OpenSees to run the program in high-performance computing (HPC). Please advise me for getting the source code that can use Linux to run the program. The current window version of OpenSees in not accepting in the Linux system. I need to run parallel computing...

Hi Everyone, I am using the KikuchiAikenLRB Material following the link below: http://opensees.berkeley.edu/wiki/index.php/KikuchiAikenLRB_Material When I run the code, I am unable to get the hysteric response greater than strain level of 4. If I change the total thickneess of the rubber, I got the ...

Hi everyone,

I have also same modeling issue for BRB. Please provide some important modeling concern to improve the BRB model and selecting appropriate material model.

Dear Shahroozbral,

Did you solve the BRB frame with acceptable results? If you solve the modeling issues, please share your findings to improve the BRB model.

Hi Everyone,

Has anyone solved the BRB model issues? If so, Please provide important finding of the model for improving the response of the BRB.

Hi Saharnaz,

Have to check the period of the frame? Could you please tell what tolerance limit you used in the analysis? I think the modeling assumptions in the brb may influence the respone of the brb, which may change your response.

Dear Dr. Frank,

Thank you for your valuable feedback.

Dear Dr. Frank, Thank you for your feedback that helps to improve model especially the panel zone modelling and its parameters. Now, I got the reasonable response with some changes in my model. I have one issue for assigning panel zone shear model properties that make the response changes significan...

Dear All, Although I got time period of 0.58 sec for a simple one story model with elastic model, I got following message while solving the same one story model with panel zone. OpenSees > source onestory.pz.tcl.tcl ProfileSPDLinDirectSolver::solve() - aii < 0 (i, aii): (6, 0) ProfileSPDLinDirectSol...

Hi, 1. You have to apply the portion of the gravity load that comes from the space frames in between the moment resisting frame. It means that the gravity load that comes from the moment resisting frame along the perimeter should be applied in that perimeter MRF. Then, the remaining gravity loads of...

Good Afternoon, I am using the self centering material for parametric study based on the link below. http://opensees.berkeley.edu/wiki/index.php/SelfCentering_Material Although I have varied the Post-slip linear bearing from 0 to 1, I am unable to see the response of post-lip linear bearing after po...
