It's possible to do a static non linear analysis with lateral pattern of displacement impose?

ok, thanks

Excuse me Silvia I send you the file, it arrive.
tahnks for help.

Ahh!! another question but why I must check fondamental periodo of structure?

But in the manual say taht UmfPackSOE construct general sparse system of equations. Why the result is same SparseSPD.
I send you mail with my file.
thanks for reply in advance.

Excuse me Silvia, but I do the same analysis and I change only system command. The curve base shear - displacement change if I use UmfPack and SparseSPD or other system command.
therefor I would want to understand how choose the system command.
Is there any references on this topics?
thanks for help.

How can I choose the best system command for my analysis?

Anybody know what can I seek the best system command?
Thanks for answer

I do a model where end node of beam have only same rotations and vertical displacement of end column's node. the model is: ________o x | | o node of beam (I call 1) | | x node of column (I call 2) | | x & o have the same position | | | | in the model I write node node equalDOF 1 2 2 3 And I enfo...

uyzagan i tryed the model with element disp for beam and the axial deformation is 0, but the problem on the axial force is not solved.

I send e-mail to ....

Silvia le volevo porre un'altra domanda:
Ma quando la sezione di calcestruzzo si fessura il programma opera una sorta di redistribuzione dei momenti, simile a quella del Sap quando si ha un caduta di resistenza nel legame costitutivo?

Io sto effettuando delle analisi statiche non lineari su un edificio scolastico, con struttura in calcestruzzo armato, per il mio lavoro di tesi. Queste analisi sono già state svolte con IDARC e con il SAP ed io le sto rifacendo con l'OPENSEES per vedere la differenza dei risultati ottenuti utilizza...

excuse me for delay in aswer. I'm trying the model with nonlinear element and dispelement, and the result is good.
I have many difficult to explain you my object in english, can I write you in italian this?
Thanks for help

Can I use nonlinearBeamColumn and dispBeamColumn in the same model?
Thanks in advance for your help.
