Hambro D510 - Concrete Floor Systems
The D510 composite lightweight floor system is Hambro’s
shortspan alternative to answer elevated floor construction
Hybrid concrete/steel T-beams run in one direction, with
an integrated continuous slab spanning the other direction,
combining to form a mini-beam section with poured concrete.
The mini-beam section (Fy = 50,000 psi (350 MPa) min.) is
a cold-formed piece including bottom chord, top chord and
web plate. The top part of the mini-beam performs as a compression
member during the non-composite stage.
In the composite stage, the upper section of the D510 is
embedded in the concrete and acts as a continuous shear connector.
The concrete slab is reinforced with welded wire mesh. The
top chord of the D510 acts as a high chair, developing negative
moment capacity in the concrete slab, which performs as a
continuous one-way reinforced slab.
