COMPOSITE CONCRETE/STEEL
Stay-in-Place FORMWORK Professional Results
TotalJoist is a patented steel floor joist. With dovetail shaped deck and embossed ribs,
it forms a very strong permanent bond with the concrete poured onto it, and acts as
reinforcement for the slab. Composite TotalJoist combines the benefit of a
strong joist, dovetail deck and concrete, to provide a premium
concrete floor system.
Unique dovetailed steel deck provides a superior mechanical
interlock with the concrete.
Total-LEWIS Deck naturally drives heat upward for in-floor
heating applications, increasing efficiency of heat system.
Provides a solid floor feeling.

Notes
1. Spans based on the following criteria:
a. Strength
b. Deflection
i. Live load deflection limited to L/480
ii. Total load deflection limited to L/240
c. Vibration
i. Peak acceleration of the floor limited to
0.5% g in accordance with the
method outlined in AISC Design Guide 11
ii. Damping ratio of 0.05 assumed (full height partitions)
2. Dead loads shown are superimposed and are in
addition to the self weight of the floor.
