Looks like normal checking. How on earth are you getting 11k per column?

You have to submit calcs on a deck? Other than when I was doing light gage steel, I have had to submit calcs maybe 10 times in 30 years.

Sounds like the OP is just trying to confine the existing mortar. While i appreciate Pham's expertise in this area, honesty, I would just slather it with any modern mortar that reasonably matches the color and call it a day unless the contractor is on board to do testing and find a qualified mason.

I thought this was only an issue with historic brick. Why does this matter for rubble stone?

I imagine whoever designed the belt (Gates maybe) is well versed in hot versus warm conditions. Seems like it is more not finding a mix that will tolerate all the chemicals in used engine oil for that amount of time/miles. Although, Honda has been using wet belts in their small equipment engines...

Hard to imagine the bolt grade would be the limiting factor.

I disagree. Thrust from gravity seems like the bigger picture here based on the OP's original post.

Not true at all.Timing chains and phasers. Watch Ford Tech Makuloco's videos.

yup, I imagine it will have significant deflection issues.

As you will find, there is no free lunch

Unlikely you will ever get that to work out (the truss that is) Also, I would not even worry about your load spreading out. Just size the big header for the point load. You are pretty close to the end of the wall so arching action may be questionable. Do you have a mentor of any sort you can run...

1) I don't think your load will begin spreading out until it gets below the upper windows, 2) You may be thinking about this wrong. It is unusual for a truss to be putting an out-of-plane load on a wall. It is usually the other way around. i.e. the truss is bracing the wall.

AI response below. I imagine the issue is that they work fine in a laboratory but when exposed for extended periods in highly contaminated, neglected engine oil, they don't survive well. Honestly, look at the timing chains in Ford Ecoshit engines. They don't last very long either unless you...

Floor sheathing or blocking is usually fine to brace the beam. I use BCCalc occasionally and it always defaults to the beams being totally unbraced. Kind of annoying as they rarely are.

Don't think you should use repetitive member factor as the planks are not connected together.

Because the wheel load is not actually 3,000 lbs and the design values are conservative. Also, draw a free body diagram of the clear span of the plank as the length and your point load 1/2 a tire's width from the end. The shear won't be 3,000 lbs there. It will be slightly less. You also can...

The dolly has surge brakes

I can tell you when I pulled the trailer of on to the shoulder with the trailer slightly turned, the steering wheel was super tight against the lock pin. That is when I decided to use the straps instead. I think there is more going on than you may realize. Also, there is plenty of anecdotal...

I just rented one of these to tow a '98 Cabrio tomorrow. Yes U-haul says to lock the steering. Seems like a great way to break the lock pin. The pivoting tray has very limited range. Not sure what happens in a tight turn where it get maxed out? I ended up disengaing the steering lock...
