Concrete Floor Loading

[McManaman]

Hi,

I am a mechanical engineer. I would like to ask if I have a goods transporting on the concrete floor (the imposed loading = 7.5kPa), how do I know the slab will not be damaged? The dimension and weight of the goods is 3826mm(L) x 1512mm(W) x 2206mm(H) and 5503kg respectively.

Thanks a lot!

I'm not exactly sure if you are asking about surface damage or structural, but I'll assume you mean surface.

Increasing the density of the concrete (see densicrete

http://www.wicktek.com

) will certainly help, and there are also coatings ( see

http://www.spraycrete.com

) that will help a lot. I think that increasing the total density is better, since this also will improve the structural characteristics. In a perfect world you would do both.

Please note that I am not a structural engineer, and this is an opinion based on research and personal experience with concrete building materials while working with a qualified structural engineer to make sure I didn't kill myself.

Apologies in advance if I answered the wrong question.

Is this a slab on grade or a suspended slab? What is the 5500 kg load supported on? skids?, wheels? It's a little difficult to drag a 5500 kg (12K) 'box' across the floor.

I assume it's a slab on grade. If on grade, what is the sub-base like, how thick is the slab, any reinforcing, strength of concrete, age, and what is the overall construction of it?

If a suspended slab... need a lot more information, bay spacing, thickness, design loading, etc.
