Thread like this almost sound like an AI bot asking questions. But I'm unsure whether the AI is getting better or worse! :LOL:
It is almost like this is a Turing test for us.
The way I've found effective is profile cutting of the decking with full size holes which is typically done anyway. Then once the steel is laid the installers only need to drill through the supporting steel. Being M6 this is a relatively fast process. Then the tapping is done with the screws.
I'll give you credit for your honesty. But that is all.
Your role as an engineer is to assess this connection and make an informed professional judgment that it is suitable. By your own admission you don't seem to be in the position to do so.
Maybe some friendly people who know this software...
Use self tapping screws. M6 DIN 7500 work well in my experience. Or if your client is fussy use a countersunk screw but that is more work.
All the checkerplate that I use for industrial applications adopt this approach.
This was discussed in a recent thread. Minimum flexural steel requirement are for more than just crack control. They are there to stop brittle failure. There are ways around this in AS3600 but those ways probably couldn't be justified for a tower crane where flexure is at 0.9 of ultimate...
Well if we were going to split hairs it seems we have a bunch of engineers in this thread who mascaraed as an occasional businessman (or business professional).
And we have a few people in this thread who are running a business and are engineers. I'm looking at you @LOTE ! 🫡
At this stage in...
I've only vaguely followed along with this thread. But this advice stands out in my opinion. Behind that advice is the general advice of, stick within your own area of expertise! It is a simple statement but is rings true and should be at the back of your mind at all times.
Given my current...
That is an issue and you need independent advice.
What country are you in?
You should be seeking a third party building inspector, engineer, or the appropriate person in your jurisdiction. In my jurisdiction I'd go with a reputable building inspector as they are likely less expensive, have a...
I like that and probably should use that more. Although my business has consulting in the title. I rarely describe myself as a consulting engineer, I should. It is particularly important in Aus, NZ and UK as engineer is not a protected title.
I believe so. I've worked sales assistance jobs...
While some states might have that requirement. Holding a board meeting for a company isn't an engineering task. It is often not even remotely close to engineering. It is a management activity related to the company, the business if you will. I don't see how engineering ethics would come into...
I know one engineer who tries to align pretty much all his regular international holidays with engineering conferences! Or even throw I several engineering 'research' visits to ancient Greek and Roman buildings and call in all tax deductable!
Of course if you need to bring your wife 'personal...
I would say that description is accurate and your issue relies with you preconceived ideas of what a "business man" is. Sure in isolation the term "business man" conjures up images of suits and ties, briefcases, deals, money and the big corporate world. But that is a caricature.
In a strict...
Except that is not the direction I was referring to. It should be obvious to any moderately experienced structural engineer that these structures are significantly stiffer the cross portal direction as these are braced compared to the portal direction as these rely on moment frames.
Of course...
I've been meaning to post the same thing for a while. Though the rod bracing isn't really relevant unless we are talking different directions.
Portal frames of this size can often move 100mm+ in the direction of the portal framing in ultimate cases. The previous columns were pinned top and...
In the AS codes there is a clause regarding minimum steel requirements that states:
I've interpreted that for foundations like raft slabs that you don't need to meet minimum flexure steel requirements. Because they are statically indeterminant and brittle failure will not lead to collapse...
Nicks and scratches in galvanised coatings don't matter in NORMAL applications for the reason Kootk mentioned. Half the reason why a cold gold galling or hot stick galling is done is for aesthetic reasons to keep client happy and not show up your site rectifications.
Now in harsh environments...
It is a little sad, though also understandable, that so much of "engineering judgment" has been taken out of things....
Thankfully for myself many of the projects I am involved in, engineering judgment is alive a well! I'd like to believe that in "normal structures" my designs are efficient...
As a builder pointed out to me recently. He has to give a 6year warranty on the home based on local laws. It doesn't matter what the CURRENT owner agrees to regarding serviceability. If the owner in 4 years time takes issue with the outcome he will have problems.
We were discussing the...
IMO the risk/return doesn't seem make sense for an engineer to be playing those games. With longer spans and cantilevers it is pretty much all about serviceability in the residential world.
I remember seeing one of these type of designs. Except there was an ugly great column in the corner...
