If you have a circular pattern of bolts, the derivation of the bolt group moment of inertia is the SUM(Ad^2) where A is the individual...

Here's a sketch...

The 12 + 2 is usually an indication of a concrete cast-in-place joist system where the 12" represents the vertical depth of the pan...

Without resorting to actually reading the IRC, my gut response is that you'd have to have some type of connecting link over your...

Is this some kind of homework assignment?

How are those angles going to do anything? They will just be additional dead weight on the deck and take zero load, correct? They...

And so it begins - engineers using AI to design something. I may move to the high mountains far from structures.

I've either added a short shear wall at the corner (maybe in the northwest corner of your plan assuming north up). Or I've used...

Is the brick chimney to be left exposed to view in the new room? If not can't you furr out a new wall in front of the chimney and...

There is still dead load (lift beam, hoist, trolley). The payload on the hoist is live load. The live load is essentially dynamic and...

What rebar are you talking about here? The drawing you posted seems to only show reinforcement inside the foundation mat. Are there...

Depends on your situation and magnitude of shear I guess. As I mentioned above, if the shear is minimal (as most residential homes are)...

A lot of pure FE software doesn't do buckling very well.

In some cases plans/designs for residential aren't required to be sealed/stamped by a licensed engineer to secure a building permit. If...

Ok - now that XR250 mentioned this - I was perceiving a W12 braced only by decking or something on its top flange. My comments above...
