load and load bending

[odisseo 18]

hi apologies if I ask for your opinion, the question for you is certainly trivial I would just like to know if it was possible how much a box of 80x80x3 mm high 3 meters can be loaded (the pillar according to my empirical calculations should support 2,5 ton, if I have not done wrong calculations) and how much can support a trave ipe from 160 mm in half-work?( according to my calculations always 2,5 ton badly with what configuration? thanks to who will have the patience to answer (I should realize a portal x loft, 3 high 3 high, the putrella the balance of head or coast x have max resistance)?

... how much a box of 80x80x3 mm can be loaded at the tip 3 meters (the pillar according to my empirical calculations should support 2.5 ton, if I have not done wrong calculations) ...the 80x80x3 pillar brings the 2500 kg required by working to 23% of its possible

However, it is also necessary to take into account the moment of the frame union of the structure

... and how much can a trave ipe from 160 mm in half-work?( according to my calculations always 2.5 ton according to the tables opposite if I did not consult them badly,) ...a trave ipe 160 3 meters long brings the 2500 kg required in half-carry working to 93% considering (in favor of safety) the ends constraints as supports
... the recess as the size to have the max flexo cut resistance? with what configuration? ...from what you say it seems that you want to straighten the beam to the pillars. efforts depend on how they combine beams and pillars.
if the head of the beam is welded directly to the vertical edge of the pillar, then:
- about all the cutting is carried by the sole welding of the vertical core of the beam (tau = cut/(wire length x welding thickness < 1000 kg/cm2 approx.)
- about all the time of ink is brought welds of the two wings. each welding will have a tensile effort of about bending moment/16). 16 is the distance of the wings in cm (the bending moment must be expressed in kg*cm).

Hi.

thanks for the right advice a last question and you do not bother + if between the square head of the plantna and the surface of the putrella I interpose a plate 100x 6 /8 mm and realize a bracket are hardened and to 3/4 between pillar and cross I put a saett to 100x 100x 4 mm I make a chestnutery? how do I recommend to proceed? I'm sorry if I'm boring and I insist but I don't want to make an incorrect structure, but I still have a basic balance to get more penetration.

http://lavorielavoretti.blogspot.it.../soppalco-fai-da-te-in-solitaria-parte-1.htmlI should realize a job similar to this, only that the pillars I make them qi boxed 80x 80x 3 mm the cross with ipe 160, instead of weld it is more right to break a plate and weld it between plant and cross, to 3/74 bowls to 50 cm put a diagonal to form a rectangle triangle in order to make the structure monolithic, what do you say? thanks to those who will have the patience to answer, you could attach formula for beams and pillars thank you sorry if I am too pretentious I would like to do verification thanks again x collaboration and precious time

I'd say it's got to be designed by a qualified person. These important things are dangerous if they break... pay a professional and make you do the calculated project.
