DescriptionThe D510 composite lightweight floor system is Hambro’s shortspan alternative to answer elevated floor construction requirements.
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.
