How much can a concrete slab be loaded?

[sir j david]

I am going to place a cabinet weighing about 500 kg in the corner of a garage. The cabinet will stand on four adjustable feet. Two considerations about it:
1. What is the minimum area each foot should have to avoid damaging the slab?
2. How far from the corner/edge of the slab can you safely place a foot without the edge collapsing/damaging?

Depends on factors including design reinforcement, thickness of the slab, and concrete quality

500kg distributed over four feet is practically negligible load on a concrete slab. Regardless of construction. No problems.

Seems like I didn't include my entire post. However, regardless of construction is an exaggeration. But if it's a standard slab in a garage, there are probably no issues.

Imagine if you had four fairly hefty friends weighing >100kg each.. would you get nervous if they huddled in the corner of the garage? Still, it's probably good if the weight is distributed over as large an area/as many points as possible.

A car can have 500kg on the front wheel, so a garage slab should withstand 500kg.

You wouldn't have any problem driving a Volvo V90 into the garage, right? around 2 tons distributed on 4 wheels...

I appreciate your responses! Of course, I'm aware that cars and buddies can stand on garage floors! But I'm thinking in terms of kilograms per square centimeter; the cabinet has four adjustable feet, and each foot is just a few square centimeters. So we're talking about approximately 100 kg/square centimeter. Additionally, one foot ends up near the edge of the slab, just a couple of centimeters in.

Make the feet larger by using bigger metal pieces (or other suitable material) so the weight is distributed over a larger area.

It will hold regardless

You don't need to worry. A standard concrete withstands 3kg per mm2. Therefore, 1cm2 withstands 300kg, so just place the cabinet on the slab.

Hammer 3 nails into a board and stand on it. There's no chance the concrete will break, even if there are two or three of you on the same board.

I would have preferred to avoid that. But as I interpret the sum of the responses here, it will work out.
