Title: Size-Scale Effects on the Brittleness of Concrete Structures: Dimensional Analysis and Snap-Back Instability
Author(s): A. Carpinteri
Publication: Special Publication
Appears on pages(s): 198-236
Keywords: beams (supports); brittleness; concrete slabs; cracking (fracturing); crack propagation; dimensional analysis; fracture properties; models; reinforced concrete; stability; Structural Research
Abstract:Progressive cracking in structural elements of concrete is considered. Two simple models are applied, which, even though different, lead to similar predictions for the fracture behavior. Both virtual crack propagation model and cohesive limit analysis show a trend toward brittle behavior and catastrophical events for large structural sizes. Such a trend is fully confirmed by more refined finite element investigations and by experimental testing on plain and reinforced concrete members.
