Dear Fmk I am sorry if I post again my request. Thank you very much for all the help thus far. I just wanted to know if I was wrong to send files via email. Now you can see my files I would want confirmation on: Why does not equalDOF work? Why I can not use a very low stiffness to simulate rotationa...

Thanks fmk I have used two nodes (1 and 2) with the same coordinates at the top of the column and the command : equalDOF 1 2 1 2 3; to create a 3D hinge (tghe two nodes have to be restrained only to have the same translation). 1) What do you mean? 2) I have to run the same type of analysis used in t...

zerolenght element to simulate hinge

Dear all I have to simulate an end release (3D hinge at the top of the column ) at one extreme of a element. I have read that the solutions are two: use equalDOF (In my case it does not work; error BandLinLapcksolver::solve()-LAPACK routine returned 52...static analysis...the algoritm failed at iter...

Dear FMK

thank you a lot.

thanks for your kind answers.

I will try to use this element.

is it possible to have a reference of the author of this element (author of the theory and the author of the implementation in opensees) to study carefully the use and the geometrical limits?

thanks

Dear all Can someone help me? I thank FMk for his help but my problem for now it is not the shear deformation that I have to consider later. I am not sure about the type of element implemented in noninearbeamcolumn element and so I have not reference about the limits geometrical in the use of this e...

Dear fmk Thanks for the help. My problem is particular. I have to simulate a concentrated damage at the base of a r.c. column. The damage is concentrated at one section. This section has rebars less resistent than ones of the upper portion of the element (in this section some connections have been p...

Is it possible to remove a patch ( for ex. circular ring )of section fiber using the remove command at the end of a analysis and then continue with another analisys?
