P-Delta Effect in computer programs.
P-Delta Effect in computer programs.
(OP)
I am reading a book which said that by using commercial programs it is easy to include P-Delta effects in a single solution without haveing to use iteration technique. I am just curious how can they do that and what is the theoretical bases.
Happy New Year.

I am sorry but I don't remember the name of the book, but if you went to their website I am sure you could find it

Which book are you referring to. I don't know of any software based on beam element programming that can include P-delta effects in a single analysis. I would always think a iterative solution like Newton-Raphson's would be necessary.

On another note, there are very few real world problems that can even be set up to solve directly with a differential equation. Anything statically indeterminate CANNOT be solved directly. Think about it; the simple fact that you MUST select a trial size to solve it means that it is an iterative process. With very few exceptions (certain geometric and loading setups) your loads will depend on the geometric properties of the members so you cannot know the result before you select a trial section and you cannot finalize your section without knowing the results.

I have written a number of algorithims that iterate to a solution - you just have to know when to stop....
