Building codes typically have guidelines on max vertical rise over run. But typically for bridges you will have a construction joint at the step. AASHTO should provide guidance if you have access to the code. Some details will show an actual step and others will slope the bottom. Not really sure...
What it look like in plan view?
From a construction standpoint it will likely be poured after backfilling, it would be wise to build it with pilasters or retaining wall design methods. Is there live loads on the slab above where wheel loads will apply pressure to the wall?
Pressure wash and repoint joints, or pour a one sided wall against the existing wall. Could probably take stucco netting and anchor it then stucco over top.
In theory if idealized as a simple beam rafter wouldn’t the assumption be the strong axis is being loaded? Neglecting the lateral reactions per industry standard for pitches less than or equal to 12/12. But the section taken due to the notch would reduce the bending capacity of the purlin? If...
You will want to use PEMB manufacturer that provides stamped drawings, if you try to design it yourself you will likely end up with a much heavier and expensive building. They use in-house software to optimize their designs.
Seems like a national security, legal and ethical issue. Not sure how the laws are set up down there but in America you have to be a design professional in each state you want to practice engineering and typically government agencies require firms to meet certain criteria. You might want to...
There is stress in form work, as a former concrete mason when you snap ties there’s typically a pop since the ties are still under tension, you might not notice if the forms bond to the concrete is greater than the tension. That being said I would use foam insulation to prevent long term...
Just get some big rocks, keep the surroundings natural. If a truck is backing up to this area add a wheel stop a distance away, no damage to the truck if hit but let’s the driver know they should stop.
So best option pour a footing for the CLSM to keep the wall base pinned. Likely the precast wall was designed with soil loads on that side and relies on the floor slab and flooring to provide bracing. Investigate light weight fill that is a sand cement mix with a foam agent.
Calculate the...
