Sure, A few sketches for you are attached for your interest. Was aiming to design the leg of the frame for 400kN. The load is not equal per leg.
The frost layer comes into play for one foundation we can't get down below the frost level with that foundation due to how tight it is with existing...
My latest idea is I'm going to include a spot for a 50t hydraulic pancake jack directly under the threaded bar. That way we can measure the exact compression load we want to put into the system and the threaded collar will be able to be moved easily nearly by hand (no friction) in 10mm increments.
Hi HotRod10,
Thanks for the comment. What are your thoughts on balancing the load though during a jacking motion? Adjusting them evenly at the same time? Just coordinated 3/4 people coordinated turning nuts at the same time / risk of overloading one more than the other etc.... ?

Hi,
I am in the process of designing a heavy duty screw jack at the bases of a 6m tall support frame. We are designing it for approximately 400kN compression.
Conceptually the idea was to allow the torque / compression in the screw jack to be checked and adjusted over time from grade. The...
Thankyou Agent666. Yes I am in agreement and that was my initial plan. I was second guessing myself when I got through to the fairly large size of the foundation (3mx2mx1.5m deep) compared to some of the existing foundations on site(2mx2mx1.2m).
The thought was if it was an impact load of such...
The approach makes sense. I would be pretty conservative on the safety factor for tension / uplift for brittle bricks. I would also maybe add some reinforcing into the grout pocket to make it more ductile...

Hi, So I am designing a permanent fall arrest monorail style system. The design criteria includes 2 workers so 5000lbs each 10,000lbs as the design anchor load from Worksafe BC in my mind.
Should this load be applied all the way through for the design of the structure, beam...
