Its curious to me that the results of this doubling aren't easier to recreate. I wonder if anyone has physically tested this, I imagine there are some results out there from end plate moment test. Ideastatica looks like a very interesting piece of software. I will personally be using stiffeners.

It will be interesting to see your approach.

Run both parallel Thin-Thin =1257/bolt Thin-Thick = 1253/bolt Thick-thick = 882/bolt Interesting that even 1" plate and low forces models out to have some prying, where traditionally its assumed that the prying is negligible. I have the tension elements (bolts) as perfectly rigid, My guess is...

I was curious and put a quick model together. I am finding that these are not additive. the thin to thin has just a minor amount more tension, small enough I would consider negligible. Modeled from plate elements 8" wide flanges 14" deep all plates 1/4" thick (except where varied to check...

I ran into these same panels for the first time as well maybe two weeks ago. Mine were used for roof framing. There is a similar product apparently still available by Martin Fireproofing. They have load tables (attached) The Gypsum ones were possibly by a company called US Gypsum. I did not...

Wow that deck is cringe. I suppose the load path is the rim joist cantilevered from maybe 6 nails. From the Original post did anyone else notice the angle is attached with drywall screws? Here is One more for the party - Some 'repairs' at an apartment These boards are doubled so not as bad as...

Jerseyshore, You're spot on. Maybe this post should have been titled "Stupid stuff they do on YouTube." Ussuri, Earlier in the video they show them pouring premix bags, they go to some trouble to push the aggregate down to get a nice finish. I'm am putting it on my list to pour a sample of...

Something I have never seen before. My you tube recommended me a video on a method to dry-pour concrete. Basically screed off bagged concrete and water with a garden-hose. One video is for a slab for a chicken coop - OK no load I get it. But searching similar videos start they escalate up...

Would this be an application for a Diamond wire Saw? I only have a you-tube level knowledge of these but they look like they could do what you need. https://www.youtube.com/watch?v=xPJAFNaEVEs

A couple other options we use from time to time if you have some control over the beam size. (Option 2 may not work for composite beams.) 1 - Use a deeper beam such as W10x12 instead of W8x10 the small added weight may cost less than a complex connection. 2 - lower the W8 beam below the flange...

In our office we usually specify F1554 Gr 36 for our cast-in anchor rods. The reason for using the lower grade anchor Is that if the anchor is damaged or mis-located low it may be possible to weld an extension to the rod (Where using the higher yield Gr 55 and Gr 105 you would need to specify...

The block looks like it was specifically created to be tensioned.(Each block has a hole in it to allow for a tensioning rod). The picture reminded me of an article I read a while back in structure magazine, Link The slab looks like the picture in this article of the NABCO Dox Plank system. Its...

Thanks everyone for your opinions so far. I have expanded my google searching and have come up with a few references that are right in line with what has been said 6" - Design of Marine Facilities for the Berthing, Mooring, and Repair of Vessels 4" embedment minimum for piles not in tension...

I am trying to find a detail for timber piles into a concrete pile cap. I searched our company library, the Timber Piling Council, and checked Google and could not come up with a detail with confidence. Basically we have 12" timber piles with a concrete pile cap on grade supporting a shallow...

Thanks 77JQX, We reviewed the tank design and they have a 2" sloshing wave height shown for seismic. Would this be just converted to a pressure on the wall 2"=10.4psf? This tank is in a low seismic area (Ohio) we were not thinking seismic at first but that is a very good point.

The water level will remain the same, They don't provide any way to close up the openings at the bottom of the wall during filling or draining.

We are designing a platform that is spanning over a waste water tank. The tank has a baffle wall with the top of the baffle wall braced back to our platform. What kind of loads will the top of the baffle put on our platform? Our initial thought was that the flow at the baffle will be slow...

Could you use a real wide flanged beam? you can probably get a local fabricator to donate a piece to you. maybe even with holes and cuts (For exciting limit state demonstrations!) Or for a lighter option get an aluminum I beam. Or even lighter get a fiberglass I beam I did a quick search on...
