new to this - need reference on H-beam strengthening
(OP)
As I was mostly active in mechanical engineering (CNC machinery), I don't have much (if any) experience in structural connections.
I am trying to make a frame at home (for all the safety purists, don't worry: 1) it will be overdimensioned and 2) if it fails, I will be the only one underneath...)
I need information on the following:
When welding a piece of metal inbetween the flanges of a vertical H-profile, should I leave the corners open (not welded) or should I fully weld the plate's circumference?
I have seen examples from both practices, and I believe stress concentration is one view against a full weld.
Drawing included, the arrowed corner (+ mirrored corner) is what I need to know...
Many thanks for your views on this...

Conventional practice is to cope the corners, but fundamentally, it's not a big deal unless you have one or both of the conditions noted.

I was always taught no to will within the k distance on wide flange sections (any I shape). This was because of the residual stresses caused during the formation of the section. Applying weld in this location may cause the section to crack in this area.

Everyone knows you always insist on a sketch, so they just take every chance they can to antagonize you by making it difficult for you to get at it. Even I could open that one, it's a pdf file.
RE: new to this - need reference on H-beam strengthening
It is a mystery to me. I tried to open it several times and it kept coming up blank. Then I saved it to Desktop and tried to open it from that file...same thing, blank. When I look at the file's properties it tells me it has a size of 6.56kbytes.
I have been opening other pdf files with no problem. I dunno, maybe it's time to invest in a new computer.

The vertical (and other) beams are standard items (with radii), not self-made out of plates.
I can't explain why the pdf file won't open, I tried from another comp and didn't have any problems.
another question for dhengr, is there a problem with pdf files? do you prefer JPG? It's just pressing another button when scanning... I prefer pdf as it's an all-platform document (eg when sending notes to collegues that work on Linux comp, they cannot open PPS, word doc, excel, so most e-mail attachments are adobe files).
