Re: Concrete Cover Over WF Beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I don't see how the 3/8" of cover is going to stick and not break up into little pieces.  There was a previous post on welding 3/8" plate to the top.  Another fix would be using 3/8" thick diamond plate to you don't have a slippery flat piece of steel on top.  This assumes that there won't be some sort of floor covering applied.

What is going to stop the 3/8" of topping concrete from breaking up into little pieces over time with a little bit of movement, deflection etc? I seems awfully weak to me!

I have a case that is very similar to the following detail. I am only going to have 3/8" of concrete cover over the top of the WF beam.

Does any preparation to the beam typically done (sandblasting, applying epoxy) in order to insure the bond of the concrete to the top flange of the beam? This cover is not structural, is there a minimum cover recommended?
