help sizing pilastr beam coupling plates

[odisseo 18]

hi I kindly ask your help and your kind advice x size 4 steel plates x bind firmly through bolts 2 steel pillars hea 120 h 3 meters to a horizontal cross hea 180 l 3 meters to form a portal I would like to know that size I have to realize length thickness number holes width diameter bolts k coefficient bolts hardened clamps thanks to whom will you want to help me x your precious time I have to fill the plates and make some threads

hi am I always empirically developed the measures of the 4 plates 2 are to be welded at the base of the putrella that acts as a traverse while the other 2 are to be welded head to the pillars with its stiffening handkerchiefs as size I chose length 70 cm , width 20 cm with 14 holes from 20 mm 7 per side + 1 in tail thickness 10 mm steel , the plates of the pillar I have to fillet or put the bolts passing What do you think and conceived well or is undersized? aleggo scheme thanks for the attention I wait clarifications

Do I need to fill in or put the bolts through what you recommend? What do you think and conceived well or is undersized? allego schema thanks for the attention I wait clarifications

the plates of the threaded pillar? I imagine you mean the holes of the plates................
If it's so handy, then don't thread.

As for the dimensioning I have never been a magician in it, but........ but first I must/you must understand what it takes.
Because if you put a tank up there, maybe the structure is undersized, vice versa could be oversized.
I propose for this second hypothesis ....... if there are 15 holes (7+7+1) from 20 mm it means that you thought of using the m18 bolt.
15 for precision....... :

from 18 mm ? I do not know how to put bolts appropriate to the effort of the bond I believe to ink, the weight however is around 2000kg in half-works even if in fact never underground this load the calculation according to the tables of the materials of the profiles empirically however to the reason the plates of the columns I wanted to know if I had to realize thread biting thanks for your punctual collaboration and your precious advice, however the plates the dimensioning where I find it? what legislation there is in the matter of coupling excuses the questions are not only modest balance shoes
that criterion is used x the correct sizing thanks again x the available excuse if I take advantage of your knowledge and professional wisdom thanks to the next time

as I have already written to you:
"as regards the dimensioning I have never been a magician in it"

But surely the empirical rule of the bolt is this:
bolts m12 hole diameter 14, bolts m14 hole diameter 16 and so on.
In this way you always leave a light of a mm on the diameter of the passing hole, so that the screw can enter without effort, what guarantees the seal between the 2 pieces bolted is then the nut (with the rosette) that bites the thread of the screw.

the screw+dado combination is the bolt.

I thank you x your collaboration the speech of the holes I was aware that to say if I have to fill a hole from m 10x 1.5 practical a hole from 8,5 etc. I would like to know if I am not too pretentious the criterion or formulas x dimensional the structure of the mating plates the thickness and the possible tangles of reinforcement the various moments if it is an ink of a bond etc. we understood; thanks again x your testimony excuse if I demand too thank you x patience and for your precious time
