Scale effects in uniaxially compressed concrete specimens

摘要

The experimental nominal strength varies with specimen size. Such a phenomenon was investigated earlier by Griffith and Weibull. Recently, several models have been proposed to predict strength reduction with size increase In concrete structures. Confirmation was given of the proposed size effect laws, based on the extensive experimental Data that can be found in the literature. Direct tension, splitting, bending, shear and torsion tests have been mainly Considered. In particular, direct tension and bending have been recently analysed by Carpinteri et al.
