software

[Roberto1668]

good morning to all, sorry but are new to forums (in general). I searched in vain (it will certainly be so even after) a simple program to dimensional a loft. I would like to have a program for "bimbi" i.e. where to be able to insert the measurements of the step plate or the size of the mezzanine to be built (e.g. room 3ml * 4ml), indicate the weight / load (e.g. 250 kg/mq), thus obtaining the dimensions of the square tubes to support the loft (e.g. 10*10, 20*20 or other empty profiles) and the dimensional structure of the loft4 and more).
I thank those who will be able to help me and greet all those who will read this mine. Good day to all.

that I know a program "for children", and so maybe free, that do what you want does not exist. However you have two alternative ways (the third is to buy a calculation software for metal structures).

the first is to calculate the individual items using the various tabs you find online and perhaps even on the sites of profile manufacturers.

However for regular form lofts that you have to quickly sprinkle me I would certainly do an excel file where, in the most uncrapped version, in input insert the size of the loft, the permanent and accidental loads, the number of currents you want (so you can do more hypotheses) etc, and in output you will have the stresses on the elements (cut, moment etc.). compare them with the profiles and choose whether to use an 80x160 or a 100x140 etc. similarly implements the verifications of the connections between the elements and the masonry, also according to their type (c.a., full-similar blocks etc and then mechanical dowels, bars + resin and forward. .
for rectangular lofts you can get to automation levels of the calculation very "pinti".
if you want to do the cool you can create a database of standard profiles (commercial, with their beautiful area, w, j, inertia rays and anything else) and make sure that you already have the minimum profile that meets the checks.

Rereading me, as always I don't know if I was clear... in case you ask and if I can answer you.

Hello spider
First of all, thank you for what you have done and written. Although very clear I am not able to do as much as you write... I am a geometra that deals with managing yards and draws with autocad. Everything else is difficult for me... I hoped there was a prg where to insert dimensions and loads... and... everything done... simple simple. Oh, my God. Anyway, I thank you so much. Good continuation. . .
