Dear All,

Can anyone tell me where can I find the following paper:

" How to Introduce A New Material Into OpenSees" M. H. Scott and G. L. Fenves (2001)

Best Regards,

Dear Frank, I still have the same problem with the record in the joint element. I have already changed the convergence tolerance criteria and the number of steps as you told me...but the results are the same.. I've tried already difference K for the joint springs. What is strange for me is that for ...

Dear frank, My code is sourced from some files so it is difficult to post here all the code.. Can I send you my code by email and then you can tell me your opinion about it?? I changed the convergence tolerance criteria and the number of steps but the output that I get for the panel zone equivelent ...

Dear fmk, I still do not solve the problem.I spoke with some colleagues who have done similar analysis and they also had the same problem. Firstly I thought that the problem was because I'm using a trilinear behavior law for the panel zone. But I changed it for a elastic law with a high stiffeness a...

Thank you very much fmk. My problem is that I've done many non-linear static analysis and the results for the panel zone equivalent moment and deformation are what I expected. But when, using the same Data file, I do the transient analysis (adding the masses and changing the input from nonlinear sta...

Good afternoon, I'm modeling a steel moment resisting frame, using the joint element. If I do a Pushover analysis and do the following recorder: recorder Element -file $Dir/PZ_ShearPanel_233.out -time -ele 233 shearPanel stressStrain In the recorder file I get the load factor, the Equivalent Joint M...

Hi, I had the same problem a few weeks ago. So I decide to make a file defining the units. I use the following units definitions and the models works fine: # Units_(SI).tcl puts "Units Definition Started" set m 1.; # Define Basic Unit - Length set kg 1.; # Define Basic Unit - Mass set sec ...

Thanks... Everything is working now...I found a units problem, that was amplifying the loads... I have another question... when I do a pushover analysis, if I want to know the sequence of plastic hinges and there location .. how can I do it? I have to analyze every potential hinge section to know? T...

I have the loads apllyed in the nodes (nodal forces). I've done a test applying only one nodal force this way: pattern Plain 1 Linear {; load 9 0 50 0; } and it works... but if I apply : pattern Plain 1 Linear {; load 9 0 500000 0; } it doesn't work.., Do you know Why? There is any convergence probl...

Dear Silvia, I've done the eigen analysis and the model seems to be working correctly. I obtained the expected results, so my problem must be in the analysis procedure, but I can not figure out what it is?.. I send you all the analysis results message, " Units Definition Started Units Definitio...

Hi , I'm modeling a 2D steel frame with 5 storys and 3 bays. Everything seems fine but but when the Analysis starts I get the following error: "Analysis Objects Started WARNING - ForceBeamColumn2d::update - failed to get compatible element forces & deformations for element: 1(dW: << 784.173...
