In the previous part one of this report, prior to the discussion on the structural design of staircases of folded slabs or helicoidal shells results of analysis of elasto-plasthic behaviors of various types of reinforced concrete staircases were compared with their test results, so that the relation between their elastic limit and ultimate strength was clarified. Based on the above consequence, particularly herein for free-standing staircases in case of different angles between the horizontal projections of centerlines of their pair of flights finite element solution is obtained in an attempt to examine their mechanical characteristics, and thereupon a method of their structral desigh is proposed.
