The earthquake resistance capacity was estimated to protect the Japanese wooden structure from an earthquake disaster. In the previous study, Kiyomizu temple did not collapse for the assumed Hanaore earthquake wave. However, the Hanaore fault has a possibility to generate about twice as strong as the assumed earthquake wave Therefore, this study conducted the inelastic earthquake response analyses for stronger input waves to see the limit state of this structure. The results showed that this structure was vulnerable to twice as strong as the assumed wave due to falling of the main columns. Key Words: Hanaore earthquake wave, traditional wooden structure, earthquake response, negative stiffness 㸯 㸯㸬◊✲⫼ࡢᬒ┠ⓗ ᡃࡀᅜ ࠊࡣୡ⏺᭷ࡢᆅ㟈ᅜ࠶ ࠊᆅ㟈ᑐࡍఏ⤫ᮌ㐀ᘓ⠏≀ࡢ⪏㟈ᛶ⬟㛵ࡍ◊✲ ࠊࡀ㏆ᖺ┒⾜ ࠸ ࠋఏ⤫ᮌ㐀ᘓ⠏≀ ࠊࡣࡀᅜࡀୡ⏺㑇⏘࠶ ࠊᅜẸဨࡢ㈗㔜࡞㈈⏘࠶ ࠋఏ⤫ᮌ㐀 ᘓ⠏≀ᆅ㟈⅏ᐖᏲࡓࠊࡣᘓ≀ࡢࡑࡢࡢᣢࡘ⪏㟈ᛶ⬟ṇࡃࡋホ౯ࡍᚲせ࠶ࡀ ࠋࡇⴭ⪅ࠊࡣி㒔ࡢΎỈᑎᮏᇽᑐ㇟ࡋࠊᵓ㐀ㄪᰝࠊᖖᚤ ᐃࠊᆅ㟈ほ 㸦⥅⥆୰㸧 ࠊᰕࡢᨺᑕ ⥺㏱㐣ヨ㦂ෆ㒊ຎ᥈ᰝ ࠊᆅ㟈ᛂ⟅ゎᯒ➼⾜ࡗ ࠋࡓࡁΎỈᑎᮏᇽ ࠊࡣ⣭ࡢᠱ㐀ᙧᘧ᭷ࡍఏ⤫ᮌ 㐀ᘓ⠏≀࠶ࡢࡑࠊ⪏㟈ᛶṇࡃࡋホ౯ࡍࡇࡣ㈈㜵⅏ࡃࡁᐤࡍࡢ⪃࠼ ࠋΎỈᑎᮏᇽ࠼ᙳ㡪ࡀ࠸ࡁᛮᒙࡣⰼᢡᒙ࠶ ࠋⰼᢡᒙࡣி㒔┅ᆅࡢᮾᮾഃࡢᒣ㯄 ㏻⣙ 17km ࡓάᒙ࠶ ࠊ༡᪉ࡢ㉮⾜ᣢࡘᶓࡎᒙ࠶ࡢࡇࠋᒙࡀࡓ࠸ሙΎỈ ᑎண ࡉἼᙧࡀồ࠾ 1) ࡇࠊᐃⰼᢡᆅ㟈࠸ ࠋᅗ 1 ᐃⰼᢡᆅ㟈ࡢἼᙧ♧ ࠋࡍỈᖹ᪉ࡢࡣ⣙ 1Gࠊ㖄┤᪉ࡣ⣙ 0.3G ࠶ࠊ0.1G ㉺࠼Ỉᖹຍ㏿ᗘ ࡀ5 ⛊⛬ᗘ⥅⥆ࡍ ࠋࡇ✲◊ࡢࠊࡣⰼᢡᒙⓎ⏕ࡀᐃࡉ࠸ᆅ㟈ἼゎᯒࡋࠊΎỈᑎᮏᇽࡀಽቯࡍࡢ ⿕࡞ࡁᐖ࠸࡞ࡣ⤖࠺࠸ᯝࡀᚓ࠸ 2) ࡋࠋ ࠊࡋᐇ㝿ࡢᆅ㟈࠸࠾ࡣᐃࡉࡓᆅ㟈Ἴᙉ࠸ᆅ㟈 ࡀ᮶⬟ᛶ࠶ࡇࡑࠋ ࠊᮏ◊✲ࡣᐃ௨ᙉ࠸ᆅ㟈ἼΎỈᑎᮏᇽ⤊ࡢᒁ㝈⏺≧ែࡢホ౯┠ⓗ ࡍ ࠋ-135-
