The program considers the following slab systems: Flat Slab; Flat Plate This slab construction is generally known as . Each pan-joist system is comprised of 3 in (76 mm) thick slabs on 12 in (305 mm) deep joists at 25 in (635 mm) on center, supported by two lines of CIP concrete beams and a CIP concrete foundation wall. or 66 in. IIC-40. FILE NAME: RSIC-1TTC_TFCS_100301-2.pdf. Because there are joists in both directions, this floor system is the strongest and will have the least deflection. Gravity system - steel framing, precast concrete, concrete pan joists, or concrete flat plate Lateral system - moment frame, brace frame, or shear wall Foundation system - spread and strip footings, mat slab, piles, or drilled piers. (76 mm) deep between joists has a fire-resistance rating of from 0 to 11/2 hours. ACI 117 and ACI All three versions provide an economical, easily installed horizontal platform secured to the top chord seat angles of either conventional or composite open-web joists. This slab construction is generally known as "one-way pan joists" or "two-way pan joists". The longitudinal joists 22 have reinforcing elements 23 disposed in the lower portions of the joists to increase the tension resistance of the floor system. Concrete floor systems are reinforced slab structures designed to satisfy a range of loading and span conditions in a building. Using Floor Joist Span Tables. Depths and spacings for one-way concrete joist construction were standardized in 1932 by the U.S. . Super Stud's Corrugated steel decking can be used as a concrete pan deck for spans between joists up to 2'- 6", or as a floor underlayment for support of tile backer or other flooring materials, or a support of poured gypsum flooring. Our 28-gauge deck is hot-dip galvanized, and compatible with our Super Joist and SuperMAXX Joist and As the complexity of design and construction increases, it is imperative that both the A/E and detailer understand their responsibilities clearly. a Example: a=12'; Post Spacing=8' y Use the Joist Span table to find the acceptable joist sizes for a 12' span, 2x8s at 12" O.C., 2x10s at 16" O.C. For example, a 30" deep concrete beam with geometry offset of 0" (from level) will show as a solid line, since the top of beam and top of slab are the same. (76 mm) deep between joists has a fire-resistance rating of from 0 to 11/a hours. The concrete slab adds extra strength, allowing the joist top chord to be smaller and therefore reducing material because the joist alone does not support full design loads. The stem walls would be 8" concrete block. to 24 in., and for the 66-in. * Similarly, He r e again, the pan form can be re m o ve d quickly leaving the shores and soffit forms to support the c o n c re t e .
