Title: Concept and Background of Elastic Frame Analogies for Two-Way Slab Systems
Author(s): S. Simmonds
Publication: Special Publication
Appears on pages(s): 1-16
Keywords: analysis; design; elastic frames; history; reinforced concrete slabs
Abstract:The justification for using elastic frame analogies to determine design moments in two-way slab systems is discussed. A brief history of two-way reinforced concrete slab design leading to the current code procedures is presented. This history includes a description of the various elastic frame analogies that have existed in past codes, the reasons for changes and the research leading to improved frame analogies. This is followed by a critical review of the Equivalent Frame Method in the current code with suggestions for improving and simplifying provisions for elastic frame analogies in future codes.
