This ACI Special Publication consists of 10 papers, all of which were presented at the session in New Orleans. The current ACI 318 Building Code specifically addresses two methods for the design of two-way slabs. These methods are the Equivalent Frame Method, and the Direct Design Method. However, the Building Code also "...permits a designer to base a design directly on fundamental principles of structural mechanics provided it can be demonstrated explicity that all safety and serviceability criteria are satisfied." The papers contained in this volume should give the designer an overview of some of the different analysis and design techniques that are currently being used.
