Ramp Mesh 1

[MN91]

Dear fellow engineers,

In the attachment below is a ramp supported along the x-direction, and having the ramp-basement wall connection fixed by epoxy (y-direction).

My question is, is there any structural deficiency if the ramp steel reinforcements were placed in such a way having the Y-reinforcements placed first, then having the X-reinforcements laying on it?

Best Regards

I can't decipher your plan. Maybe someone else can. What is the span? The bottom bars should be placed first in the direction of the span.

What are the numbers? Dimensions? Not in the dreaded centimetres, I hope.

Epoxy is not a way to fix a slab to a wall.

From what I understand, you want the ramp to one way span between two walls.

And you are asking whether it's bad to lay your secondary reo down first and then the main flexural reo on top.

It's structurally inefficient as you are losing effective depth (by the diameter of your secondary bar) to the bottom main flexural steel.

Like Trenno said, the only potential issue is inefficiency if your largest moments wind up being resisted by your shallower effective depth. A 350 slab is fairly thick. The efficiency penalty ought no be that bad.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Thank you for your replies, they were quite helpful.
@hokie66, attached is a clearer sketch for your use.

Turn in your engineering membership card... I see centimeters.
