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.

这项研究集中在高强度螺栓连接上，经常使用钢结构，并进行了滑动测试和接触表面状况的测量，以评估这些连接的滑动系数改变了基于摩擦学理论的表面状况处理。因此，我们执行了两种滑动测试，该滑动测试使用了小尺寸标本来详细测量表面状况，并使用了真实的连接样品来考虑实际的滑移行为。作为这些测试的结果，在Shotblast处理的情况下，滑动系数可以通过算术平均粗糙度参数准确地估计。 RA在过去的研究的相同结果中。在通过其他材料进行表面处理的情况下，滑动系数取决于每种材料特性。
