My latest project is a 'free standing' door frame, cantilevered from the bottom. The door is a normal 3'x7' metal door. I'm at a loss for the loading. I'm thinking a load of about 200lbs horiz at mid height. There is no design attack resistance required. Is there a standard or reference for...

I saw a webinar a couple days back on Concrete. It was excellent, semi-technical and current. It was one of the better webinars I've seen. If you want to see it: https://bcove.video/41cQdLE

I have a connection issue with attaching a plate to a 4" thick precast panel. The load is approx 7K shared by two fasteners. I'm planning to use the following. Can anyone see any issues with this? I can vary any of the values. Concrete tensile strength is about 100 psi; I assume the precast...

With CSA S16, is there a maximum bolt spacing for fastener design? I could not find a reference to a maximum spacing. This is for an A325 bolted connection. Thanks

I don't know if this copies the thread. For Python guys... See 3:05. It didn't copy the thread location.

China has just released a new Open Sourced AI program that's nearly as good as any available, and better than them for some tasks. It's called 'DeepSeek' and is available for download. There are several versions depending on the size of the problem and the smaller versions can run on a normal...

What type of electrode would you use for fillet welding of Corten Steel? SMAW (stick) electrodes. I've heard of using E7018-W electrodes. What does the W stand for? Is there anything I should be careful of?

One of my current projects has the contractor welding 3/4" dia headed studs to an existing plate. The existing plate is HDG. I need the coating ground off prior to welding the stud. How far beyond the stud surface should the zinc be removed. I've usually used 1/2", but am thinking this may...

I'm looking for a self tapping fastener with a flat head that can be used for 1/8" thick material. I also need design load capacities for the screws. Can anyone suggest a supplier and fastener? Size to be #10 or larger and load is less than 500 or 600 lbs. It's in a non-corrosive...

"At least seven people were killed and several others injured Saturday after part of a ferry dock collapsed on Georgia’s Sapelo Island, according to the Georgia Department of Natural Resources. It happened as crowds gathered on the island for a celebration of its tiny Gullah-Geechee community...

This is an Excel workalike... When I copy and paste values for a new beam, it pastes the formulae values in the cells, rather than the formulae. It used to copy the formulae so it was just a matter of changing the beam size from the AISC spreadsheet. I suspect I may have inadvertently changed...

On an earlier project a contractor cot a 12" HC Plank in half. The HC Plank is supported and the remaining two parts have about 4x the reinforcing needed and are over reinforced. Is it necessary to core drill to cut the added strands at 4' centres is so? I'm trying to reach out to the...

From Oct to mid Dec, I had a couple of large complicated projects. I neglected my normal exercising. Mid-Dec, my son, daughter and myself walked to Tim Hortons for some food. I was exhausted when I got there. It was about three blocks. I had lunch with an electrical engineer the next day...

I understand these can be fairly large and the wood joinery of the connections is quite exquisite. Some of these structures have existed for centuries in a high seismic area. Has there ever been a study of these connections with their respect to their resistance to seismic events...
