Abstract
After theoretical derivation of the general form of the size effect formula for beam shear in the preceding Part I, this Part II presents experimental verification by least-square fitting of those existing individual data sets that have a broad size range. Subsequently, empirical prediction formulas for the size effect parameters, consisting of the asymptotic small-size strength and the transitional size , are calibrated by least-square regression of (1) a recent American Concrete Institute database with 398 data points, and (2) a combination of this database with large-scale Japanese tests and Northwestern reduced-scale model tests. Previous alternative proposals for dealing with the size effect in beam shear are also discussed.
