This research focused on high strength bolted connections used steel structures frequently, and carried out slip tests and measurements of condition of contact surface in order to evaluate the slip coefficients of these connections changed treatment of surface condition based on tribology theory. Therefore we executed the two kinds of slip test which used small size specimens to measure the surface condition in detail and used realbolted connection specimens to consider the real slip behavior. As the results of these tests, in the case of shotblast treatment, the slip coefficient can accurately estimate by the arithmetic average roughness parameter; Ra in the same result of past researches. And in the case of the surface treatment by other material, slip coefficients dependon the each material properties.
