What is it with engineers and bikes?
I have a Colnago CT-1 (Campy)
A Cannondale Six13 (Campy)
A Kona Jake the Snake Cyclocross bike
A Catamount MTB
2 Santa Cruz MTBs (one is a 29)
Calculators:
1 HP48GX
3 HP48G
I HP 49G+ (The buttons suck.)
An HP 35s
AND......
A Deluxe Edition HP 15C that I...
I agree with Dik and Dave.
I had to design a reactor foundation on one of my solar projects.
Fiberglass was considered, but in the end, I just designed it as unreinforced concrete.

Well, crap!!!
I didn't realize SlideRuleEra's site was down.
SRE,
Thanks so much for everything you have contributed!!!
I downloaded many valuable publications from your website!!!
Now, if I can just remember where I saved them.....
I have an upcoming project where the face of the CMU in a segmental retaining wall has degraded. In one section, you can see the interlocking pin for the CMU and the gravel is slightly coming through.
I suspect the freeze\thaw cycles as the main culprit in the degradation of the materials. The...
Long ago....
The load combination used to be 0.9DL + 1.5WL for the 1.5 factor of safety.
The thought behind the 0.9DL, is, we, as engineers, may put a little too much load into the DL so it was reduced by 10%
So.....
ASD load combination of 0.6DL + 1.0WL
is really:
(2/3)(0.9DL + 1.5WL) => 0.6DL...
Well, it's not a confidential client, so I assume I can share my calculations.

retired13,
Thanks! The 1st Edition was the most difficult to get. I'd see them on eBay for hundreds of dollars. I went to powellsbooks.com, and looked for it. Of course they didn't have it, but there was a button to "Notify me when it came available." So I clicked it. It took a few months, but...
Ooooooooo!
I do have a couple of copies of the Bethlehem Steel Manual, at home in my "Geek Library". I also house AISC Steel Manuals editions 1 through 9, because I am such a geek.
Thanks guys!
O.K. This is a little bit embarrassing...….
In my 25 years of structural engineering, I have never had to call out a crane rail on a drawing. Do I just say ASCE 70 CRANE RAIL? Or is there a standard for calling them out?
Thanks in advance.
First, Engin1, write down all of your thoughts based on your experience and guidance you have received from here or elsewhere, and take them to your boss on how to approach it going through your thoughts. Ultimately, he's the one that has to sign it, and if he thinks you have been chasing a...
Thanks guys!
Ugh.... Now my head hurts worse. I have members failing under DL only, which, since the building has been there since the mid '50s, we know is not possible.
Guess it depends on how far you're cantilevering. If it couldn't be picked up by a WT section as in the upper detail, I would go with a combination of the upper detail and the lower detail...
