In this paper, as fundamental steps for quantitative analysis of frictional surface in high strength bolted joints by surface roughness, the influence of rust on steel plate to slip strength and relation between surface roughness and slip coefficient will be proved by the roughness measurement equipment and the microphotograph. They are offered to the experiments of roughness measurement and slip tests. As s result, the difference was observed between rust type and nonrust type on the frictional surface in slip mechanism. The quantitative estimation of frictional surface came to forcast from roughness coefficient Rmax or Ra. And these results are used at the time of revision on JASS6 in the term of 1991. On succeeding to the last paper, the study and experiment is discribed minutely about frictional surface by non rust treatment, in this article.
