LIGHT WEIGHT COMPOSITE FLOOR SYSTEM

Easily constructed using common tools and construction methods, NJIT’s Light Weight Composite Floor System offer advantages over non-composite and other traditional composite flooring systems that include less material, lighter weight, lower cost, less overall “embodied” energy, and significant increases in floor strength (40%) and ductility (60%).
- Homes and other residential buildings
- Low-rise commercial buildings (up to 5 or 6 stories)
- Small parking decks in tight, “mixed use” situations
- Foundation walls and Tilt-up wall systems
- Explosive resistant buildings for military use
- Design may afford lower material cost per square foot than non-composite floor systems as well as reduced floor height due to its low profile
- Option to pre-fabricate components off-site and transport to job sites permits reduced on-site assembly time and overall easier assembly
- Design may minimize the need for sophisticated quality control measures to achieve a requisite load capacity
- Ability to construct with open web light weight joists allows for better accommodation of building piping and ductwork
- Less material used to create a stronger floor renders the CFS a “green”, more environmentally friendly composite flooring option
NJIT’s Composite Floor System (“CFS”) comprises a support member, a deck material coupled to the support member, a transfer member coupled to the support member, and a slab as illustrated in FIG. 1 at right. The CFS can be easily constructed using common tools and construction methods with readily available materials such as concrete and steel. The CFS’ chief advantages over non-composite and other traditional composite flooring systems include less material, lighter weight, lower cost, less overall “embodied” energy, and significant increases in floor strength (40%) and ductility (60%). FIG. 2 below illustrates the CFS’ ability to withstand high deflection without losing strength.
FIG. 1 above depicts the uniqueness of this composite design. The shear transfer member 12 is coupled through the decking 4 to the support member 8. The cuts and folds 22 allow for an increase in transfer of shear forces.
