Re: Braced Length of Steel Beam W/ Formed Slab

You do need to lock the compression flange mechanically into the concrete. Do not depend on friction between the top surface and the underside of the  concrete to provide lateral bracing.

Subject: Braced Length of Steel Beam W/ Formed Slab

What would be considered the unbraced length of a beam supporting a concrete slab if no steel deck is used?  How is lateral bracing of the compression flange achieved?  Is it through the cement bond of the concrete and the top surface of the beam flange?  Are mechanical anchors of some kind required?
