Port Liberte Apartments
Port Liberte, a large apartment complex on the waterfront in Jersey City, New Jersey, successfully displays MDGI’s open-web structural floor framing system.
The floor framing is designed around our composite open-web joists and composite floor trusses. Our floor system consists of modified open-web steel joists on composite trusses with a gypsum ceiling attached to the joist bottom chords. Adequate space is left available, above the gypsum ceiling, for other trades to run ducts, sprinklers, electrical, etc., in any direction throughout the floor-ceiling envelope.
The patented design begins with joists that are fabricated with the webs projecting above the top chords. A customized, pre-punched, corrugated deck is placed over multiple spans and locked in place with wedge devices placed throughout the webs. Pre-formed pans are fitted around the joist bearing ends to allow the cast-in-place concrete to flow down onto the supporting beams and trusses, allowing them to become composite with the concrete. A mesh reinforced concrete slab is placed over the assembly, encasing the joist webs and the end bearing.
The system has a two-hour fire rating with gypsum or acoustical ceilings.
Bonded to the poured-in-place concrete slabs, the joists and trusses are stronger and lighter and provide an extremely stiff horizontal diaphragm to resist wind and seismic forces. Steel tonnage and labor are reduced, allowing substantial cost savings.
Our composite joist system has been successfully used in schools, office buildings, nursing homes, open parking garages and other structures. This system is available for use anywhere in the U.S.
