Recently, I’ve come across a finish treatment called ‘Shou Sugi Ban’. It was developed in Japan and consists of finishing exterior wood surfaces with a light ‘char’. This apparently provides a durable surface.
The improvements include making the surface more water resistand by closing open...
I have an unusual canopy connection with W12x30 beams framing into an HSS 8x8x0.375 column. They connect at different levels. There is a continuation of the beam on the opposite side of the column. I'm planning to field weld 5/8" end plates on the beam ends to the face of the columns as shown...

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:

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
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...

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...
