Restoration work of masonry walls of time-honored castles in Japan necessitates the knowledge of structural mechanics of masonry walls. The paper presented here deals with stability of the TSUKIISHIBU section in the wall structure under long-term load; the TSUKIISHIBU section represents the whole part of the masonry wall structure excluding corner. The stability was investigated in three aspects. First, formulae to get critical heights of masonry walls were introduced under conditions of critical failure mechanisms. The critical heights concerning such variables as slope angles of the walls and internal friction angles between stone blocks and of back fill soil were calculated and design curves were drawn. Second, a safety factor of masonry walls at critical failure mechanisms was proposed. Utilization of this safety factor led us to various useful information regarding to the stability of masonry wall structure. Last, mechanical implication of the concave shape of masonry walls which is characteristic to Japanese castle was clarified.
