2d structure resolution software

[peloritano]

Hello everyone.........
I turned a little on the forum looking for what I need but I couldn't find anything and for this reason I turn to you.
I would need a very simple software that allows to solve 2d rectangular structures symbolically.
I'll explain...
I have a structure that is solicited by concentrated loads f1 f2 etc and distributed loads q1 q2 etc. each rod is characterized by ej....
(I attach an image)

the software should provide me with the binding reactions and the cinematic parameters of the individual knots according to the f forces, q loads and the characteristics of the individual ej rods.
Turning on the sites of the various universities, I have come across many software that do this but in a numerical way (i.e. I can't force f but its value to e.g. 10 n)
Does anyone have a solution to my problem? ?
all this has the purpose of doing a prior analysis of the structure so as to be able to assess possible improvements of the same

I recommend you multiframe. simple and versatile software. I think he's doing your job.

there is a beautiful free program that makes 2d travatures using the theory of continuous and is called ftool.

I understood what you want to get and for this it is enough to insert a basic measure l0=1 and express the remaining as a ratio l/l0. then you can do the same with the parameters like the module of young and the moments of inertia, the areas etcc.. if you have distinct forces just apply them one at a time and then combine the results. You'll see that with practice you'll understand how to do it.
then you can use the software you want. I prefer frame2d of ice creams (which I have been using for many years):http://gelfi.unibs.it/software/programmi_studenti.html
