Abstract

Slip coefficients of high strength bolted connections with pre-slide contact surfaces are important issue to be considered when combined connections of welded joints and bolted joints are used for the connections in I-section girders. In this paper, the slip coefficients of bolted joints,which slid on the condition of bolts being tightened up to 60% of design level and then the bolts were tightened up to the deign level are discussed through a series of experiments in which the direction and the amount of pre-slide are set as the parameters. The test results suggest that the slip coefficient ofjoints with pre-slide contact surfaces is lower than that of the bolted connections without pre-slide surfaces,but the differences are about 20% at most.
