D500

D500The Hambro® D500 Floor System combines composite joists with poured concrete, developing a hybrid concrete / steel T-beam running in one direction and an integrated, continuous slab in the opposite direction. The D500 System utilizes reusable Rollbars® and plywood forms.

The bottom chord (min. Fy 50psi) acts as a tension member during both the concreting stage and the service life. The web system, consisting of bent rods, (min. Fy 44psi) ties the top and bottom chords together and resists the vertical shears in the conventional truss manner.

Hambro® D500's patented 13 gauge S-shaped top chord section (min. Fy 50,000 psi) has four basic functions:

  1. It is the compression member of the joist during the non-composite concreting stage. The system is not typically propped.
  2. It is a “high chair” for the welded wire mesh, developing negative moment capacity in the concrete slab where it is required over the joist top chord.
  3. It supports the slab forming system
  4. It automatically becomes a continuous shear connector for the composite stage
