strip footings under small object?

strip footings under small object?

strip footings under small object?

(OP)
I am dealing with a small object (something like a shed). Walls are masonry and on top is RC slab 140 mm thick.
Object dimensions are: 5,50 m x 1,90 m (top view) and approx. 2,50 high.

Footings wont be heavily loaded but Im wondering about soil settlements if I choose option #1.
Id like to choose option #2 but Im worried that strip footings along the whole object are not necessary at all.








Also - canopy's columns are anchored to this object so I really dont want that glass on top of canopy crack or something becauese of different soil settlements
Opinions?








RE: strip footings under small object?

If you don't want movement, then a shallow foundation system is not the best option.

If some movement can be tolerated, and it's lightly loaded, you could look at a thickened edge slab on properly compacted base material.

Either way, you'll want some input from a local geotechnical engineer

RE: strip footings under small object?

Option 2 + independent ground slab is how its done in your area.

RE: strip footings under small object?

If no movement, can you use an 6" or 8" slab on voidform with friction or 'screw' piles? else, a stiffened slab is the way to go...

Why the suggestions when you don't know the ground co0nditons. Peat? Rock, Gravel, etc.
