The design example, “Design a Concrete Floor System using the Pan and Joist System,” is a detailed engineered design of a nonprestressed reinforced concrete pan and joist floor system for an office building that spans 24 ft between supports. The design is in accordance with ACI 318-14 Building Code for Structural Concrete. The design is for a 30 in. deep prefabricated joist form using welded wire and wire reinforcement in the floor pan and joist, respectively.

ACI Committee E702, “Designing Concrete Structures Committee,” is part of the ACI Educational Committee structure. Their mission is to develop educational programs and instructional materials within the area of design. The committee has developed numerous design examples to illustrate the use of various ACI documents. These examples provide step-by-step calculations with references to applicable code provisions for common member design problems and may also include calculations for common concrete testing procedures, field data analysis, or evaluations.
