Abstract

 As for on-site of the maintenance and strengthening work for steel bridges, the high strength bolted friction type joints are often applied. But, the surface preparation of the existing steel member may not be able to be processed abrasive blast-cleaning depending on site conditions. Therefore, the slippage tests were carried out using splice plates processed the inorganic zinc rich paint on surface and connected plates varied surface roughness on surface. As a result of the slip test, it was found that the slip factor and surface roughness have a linear relationship up to painted 75μm thickness of inorganic zinc-rich paint. And it is proposed that in case that painted 50μm~150μm thickness of inorganic zinc-rich paint, the slip factor is 0.4 in case of Ra (arithmetic mean estimation) > 5μm, but it is 0.2 in case of Ra < 5μm.
