Gentlemen… 2

[MIStructE_IRE]

Hi there,

I was active on this forum for years.. One of my last threads on this forum was about getting out of engineering altogether..

I have worked in the industry for some time. I’ve designed some crazy shit other engineers shy’d away from and have worked in many corners of the work. I have been very proud of the stuff I’ve designed and for a long time really loved what I did. I also felt I contributed on here quite a bit.

Last summer, I had a work related burnout/breakdown. It was the lowest point of my life. It really was an experience, somewhere I never would have seen myself going! But thats what lift is all about!

I‘m sure there are many new faces here, but I want the guys I do, and did, know, to know that I’m back baby! I’m back in the industry and back to my old self.

I hope you all cope with the responsibilities of engineering better than I did!

Thank you all

Good to see you back! Sorry to hear of your burnout, but every experience provides an opportunity to learn something new. I wish you all the best!

 

[SWComposites]

Welcome back! Good to hear you are doing well.
I myself was pretty burned out when I retired (mostly) last year.

 

[hokie66]

It is good to hear from you again, and good news from Ireland is always appreciated. Now that you have recovered from your down time, be sure to take time to smell the roses.

Welcome back... the stuff you note is what I live for... always have. I have a low boredom threashold. Some of it is just little stuff... but interesting, nonetheless.

Lol, good question, I’m not actually sure if shamrocks have a scent.. let me get back to you on that!

MIStructE_IRE:
Good to see you back here on ET and back into real life again. And, good-on-you for the recovery and rebound. Life is a crazy thing, and our profession is no less so. They all seem to want their solution yesterday, whatever you charge them is way too much, and you can’t drag enough info. out of them to make sense of that they really want (really need, many times that’s two diff. things). They seem to have little appreciation for our input, it takes too long, just slows things down, can’t you just stamp what we cobbled together, and then, they do expect you to act as the insurer of last resort, when things go wrong, even though they felt put-upon when you asked some questions to further your design. Like you and Dik imply, I always liked the special stuff, the crazy or unusual stuff, that was my beard-n-butter. I did get tired of simple beams and canti’s. of diff. lengths, spacings, and loadings, through an Arch. who hoped to bitch enough about the structural cost so he could afford pink marble counter tops. Many times, my work was after they already had their tit in the rigger because they thought they didn’t need an SE’s or ME’s help in the first place, and when the bull they shot started holding up the job, the bldg. inspector red flagged it or the industrial customer wouldn’t accept their half baked design ideas, they appreciated a real engineer’s knowledge, experience and involvement, at a reasonable fee, to fix their mess, and get the job moving again. All of a sudden, they had a whole new appreciation for an engineer’s involvement, ad would pay you for your work.

Welcome back.

Nearly everything living has a scent, even if it's to just smell like a weed.

Whether it evokes a feeling of goodness because it's a GOOD scent, is another matter altogether.

MIStructE_IRE, I just got home from a visit to Ireland and noticed a couple buildings under construction in Dublin using castellated beams (with round holes). Is this common?

 

[hokie66]

Will defer to our Irish friend as to whether they are common, but I don't think round hole fit the definition of castellated.

 

[dik]

Doing a search... it shows them as both round and hex... the hex is to save material by using a lesser depth; that was the original intent, for long spans with light shear forces. Analysis is similar for both. I guess with laser cutting it's pretty easy to accommodate a circular opening.

[hokie66]

Circular holes are similar in analysis, but they are not 'castellated'. Language matters.

 

[MHobbs]

hokie66 would you use the term cellular for circular holes in the web?
In my experience while cellular is the more specific term it would still be considered a subset of castellated.

 

[hokie66]

Cellular, yes. Castellated, no. But then the language may have been bastardized since I learned how to make a castellated beam.

 

[kipfoot]

Language matters

I agree with this and appreciate the clarification. The term I should have used is 'cellular beam'
AISC Design Guide 31: Castellated and Cellular Beam Design

I also came across a company in North Carolina that manufactures these, so perhaps it's not as uncommon as I believe.

 

[phamENG]

They don't get used often. Mostly for AESS applications, as I understand it. I spoke to a fabricator about them during the peak of the joist shortage about whether or not the high prices and lead times would make castellated beams cost effective (cellular usually are not due to the additional waste - castellated just has a little bit at the ends). His answer was no - just go with a bigger beam. The size project you'd need to have the material savings start offsetting the labor costs is pretty bit (don't recall the numbers he threw out, but bigger than the sort of jobs I usually get to see). Now if you have a dedicated company with their tooling set up to churn these out, maybe it could start to make some sense.
