Dear Friend Did your other algorithms, as mentioned in the pushover script above, give the same errors? You can play with load increment DIncr.Or, Sometime the material which are used in the model may be the problem for convergence problem, like if it has any sharp changes in its definition. In that...

Dear friend
Please attach detailed account of your error message from opensees in FB or Dropbox, and share the link here

Dear Friend, Can you post your code?

It all depends on the type of analysis and element you want to employ in your model. For example, in case of linear analysis , if elastic beam column element is used, reinforcement details are not required.But, if you wish to carry out nonlinear analysis, then of course you need to know reinforcemen...

Dear Friend, Have tried as per the protocol I mentioned ? See, say there are two units tcl files, then you are calling one file at start of your code. Now comes the definition of your BondSlip material which requires the units in psi..So just above the line where you define the material, you call th...

Dear Friend, Why don't you try creating two different system of units tcl files and source the file at just before appropriate places? For example, you have units system in N.mm.sec at start of your code, then if you want to define BondSlip material, you source psi based units tcl file. Once that de...

Dear Friend, First of all OpenSees does not have any option like SAP2000 or ETABS where you can easily change your units system. OpenSees allows the user to adopt the basic units system (N-mm-sec, kN-m-sec etc). Adopt anyone system as you wish, but be consistent with what units system throughout you...

Friend, why don't you try executing your OpenSees file through command prompt window? It will keep your error message alive.

Dear Friend, You can try different algorithms and displacement increment steps in your analysis section. Can you tell me the different materials that you used?

Dear Mr. Selimgunay Thanks for your reply. Actually I have already created the model. The issue is that it throws error which it seems regarding connectivity problem (kind of U(i, i)=0). I am using zerlength element with steel02 as my material for rotational spring. I saw an example problem using co...

Dear Mr. Giovannimilan
Have you done with your model? I also need a reference 3d lumped plasticity model for my work.

Dear Mr. Satyam
Did you solve the issue? I too face the same here.

Dear community I was modeling 3D RC building with simple one bay-by-one bay-by-one story configuration by concentrated plasticity approach. I am having problems in running the code. It throws error which I discussed with some of our community members . They said it's related to connectivity problem....

Thanks a lot Mr. Jhno..It was useful.

Dear Friend I used the following procedure to find the maximum value in one of my code. Please try it for your case if it works. # This section reads the data from your DBase.out file i.e. displacements set fid01 [open DBase.out r]; set file_Data [read $fid01]; close $fid01; set data [split $file_Da...
