The use of adhesive and adhesive/rivet or spot combined bonding methods to join steel plates has been increasing recently because of the high joint efficiency thus obtained. In this study, the tensile shear strengths of adhesive and adhesive/rivet combined joints were statistically evaluated. The probability of failure was calculated for the two kinds of joints, rivet and adhesive/rivet combined joints. Each data set was then plotted using normal, Weibull and doubly exponential functions. In addition, the effcts of the combination of adhesive with rivet on mean tensile shear strength and coefficient of variation were investigated. The main results obtained are summarized as follows ; (1) The strength distribution of adhesive joint was well approximated by Weibull or doubly exponential distribution function. However, in the case that the tensile shear strength is considerably improved by combination with rivet, the strength values of the combined joints do not form a straight line on any of the normal, Weibull and doubly exponential distribution graph paper. (2) With increasing ratio of strength of rivet joint to that of adhesive joint, the mean strength of the combined joints increased and the coefficient of variation decreased.
