Abstract
In this study, for rationalization of high-strength friction grip bolted joints (hereinafter called H.S.F.G. bolted joints) in rationalized plate girder bridges, organic and inorganic zinc-rich paints with high slip factor were developed and their slip factor, relaxation characteristics and durability were examined through some kinds of performance tests. Furthermore as results of tentative calculations the number of high-strength bolts, painting area and weight of splices can be reduced compared with conventional design by using developed paint with high slip factor.
