“…P2-15 and B2-10 (PB) are 2face friction joints, the former with inorganic zinc and the latter with blasted specimens. P1-15 and B1-10 (PB) are 1-face friction joints, the former with inorganic zinc and the latter with blasted specimens [7]. A structural steel SM490Y was used for the base plate and a connecting plate of the specimens, and F10T high-strength bolts (nominal diameter M22, length beneath the head 90 mm) were used.…”

“…However, experimentally obtained friction coefficients μ have dispersion even if they have been made by the same contact surface specification. It could be considered that the micro surface condition is ununiformed for many reasons, for example, the spatial dispersion in one surface [6], the number of contact surfaces [7], bolt columns [8], and so on. Experimental results showed that the friction coefficient of a double-lap bolt joint is slightly higher than that of a singlelap bolt joint both in IOZ and blasted surface [7], and friction coefficients also varied when the number of bolt columns changed [8].…”

In this study, the aim is to deduce the static friction limit of contact interfaces in bolt friction joints by analyzing other bolt friction joints with the same contact surface but in a different shape. By using the Weibull mathematical distribution to deal with microelements on the contact surface, the friction limit of a certain type of bolt connection was statistically predicted from other types of bolt connections with the same contact surface. As a result, this research succeeded to predict the friction limit of bolt joints with different numbers of contact surfaces and with different numbers of bolt rows. Another result of this research both the stress ratio and the Weibull stress ratio showed a high prediction accuracy.
