Probabilistic Models for Shear Bond Strength of Clay and Fly Ash Bricks

Abstract

In the current investigation, ninety fly ash and clay brick masonry triplets are prepared with three different grades of mortar mix. The shear bond strength of prepared samples is tested and analyzed on an extended statistical domain. The test data obtained from the experiments conducted was statistically analyzed for fifty-eight selected probability distribution functions with two, three and four parameters using the computer program EasyFit 5.6 Professional. The two Goodness of Fit tests, namely Kolmogorov-Smirnov and Anderson-Darling, are carried out to choose the best-fit model out of it for the shear bond strength parameter of clay and fly ash brick masonry. Different Goodness of Fit tests suggest different statistic and rank for different distributions, but in all the case Johnson SB distribution is found best to portray the variability in shear bond strength.
