Hambro D500 - Concrete Floor Systems
Trust your elevated floor system to our concrete composite
experts. The Hambro D500TM composite floor system is your
answer to solid, reliable elevated slabs supported by proven
floor joists.
This is achieved by embedding a Hambro composite steel floor
joist in poured concrete. Concrete and steel T-beams run in
one direction with the integrated, continous slab in the opposite
direction.
Hambro’s floor joist bottom chord (Fy 350 MPa min.
or Fy 50,000 psi min.) acts as a tension member when the concrete
is being poured, and continues to serve that purpose during
the service life of the floor. The web, tying top and bottom
chords together, is made of bent rods Fy 300 MPa min. or Fy
44,000 psi min. (continuous by design).
The web resists vertical shear in a conventional manner.
The patented 13-gauge top chord of the floor joist (Fy 350
MPa min. or Fy 50,000 psi min.) acts as a compression member
during the non-composite stage.
In the composite stage, the top chord of the floor joist
is embedded in the concrete and acts as a continous shear
connector. The concrete slab is reinforced with welded wire
mesh. The top chord functions as a "high chair",
developing negative moment capacity in the concrete slab causing
it to behave as a continuous, one-way reinforced slab.
