Retaining wall above capping beam 1

[Uzs1]

Hi,

I have situation where I have to run a 1.4m high retaining wall above capping beam which are sit on top beam piers spaced at 1.5m.

The overturning moment from this 1.4m retaining wall is about 10kNm/m and I have check the torsion capacity of the capping beam and it is working fine. I have also checked the bending capacity of the piers and they are also okay. But I am concerned that I might miss something. Has anyone done this before? What are your thoughts? Thank you.

Capping beam is 600mm deep so enough development length for bars from block walls

Is this temporary excavation pit with shoring walls ? You should check the tip deflection of wall and pier ..

I would suggest slope if does not hinder any work..

If you put garbage in a computer nothing comes out but garbage. But this garbage, having passed through a very expensive machine, is somehow ennobled and none dare criticize it. ( ANONYMOUS )

Thanks HTURKAK

It is not temporary. I did have this slope in my design and have checked the deflection. That slope will then have backfill.
I am concerned about using the torsion of capping beam for retaining.

For a 1.4m height of soil, I'd be surprised if torsion was an issue. Truth be told, my workplace doesn't even bother to check it

Why yes, I do in fact have no idea what I'm talking about

Hell yes, I celebrate this kind of of truth telling.
