In this paper, the seismic performance of Yamada’s house located in Arimatsu district, Nagoya city is evaluated based on the measurement survey. The target house was built about 220 years ago, and experienced several minor changes of the plan. We investigated the arrangement of the seismic resisting walls, and calculated the weight of the whole building. In the first floor, many of the walls are positioned both sides of the building in the transverse direction, and there are few in the longitudinal direction. By a spectral response analysis, it was found that the seismic performance in the longitudinal direction may be insufficient. Keywords : Traditional timber building, Arimatsu district, Seismic performance evaluation, Response analysis. 㧝㧚ߪߓ߼ߦ ᐔᚑ23ᐕ4᦬߹ߢߦో࿖ߢ91ߩ࿾඙߇㊀ⷐવ⛔⊛ᑪㅧ‛⟲଻ሽ࿾඙㧔㊀વᑪ࿾඙㧕ߦᜰቯߐࠇ‫ⴕޔ‬᡽ߦࠃ ࠆ⾗㊄⊛េഥߩਅ‫ޔ‬ᱧผ⊛ⴝਗߺߩ଻ో߿વ⛔↥ᬺߩ⛮ᛚߥߤߩขࠅ⚵ߺ߇ⴕࠊࠇߡ޿ࠆ‫ޔߒ߆ߒޕ‬વ⛔⊛ ᑪㅧ‛ࠍ᦭ߒߡ޿ࠆߦ߽㑐ࠊࠄߕ‫ޔ‬㊀વᑪ࿾඙ߦᜰቯߐࠇߡ޿ߥ޿࿾ၞߢߪ‫ޔ‬૑᳃ߩㆊ⇹߿㜞㦂ൻ‫ޔ‬࿾ၞ↥ ᬺߩ⴮ㅌߥߤߩ␠ળ⊛⢛᥊ߦࠃࠅ‫ޔ‬વ⛔⊛ᑪㅧ‛ߩ⸃૕߿᡼⟎‫ޔ‬ή㈩ᘦߥჇᡷ▽ߥߤ߇ㅴߺ‫ޔ‬ᱧผ⊛ⴝਗߺ ߇ᕆㅦߦᄬࠊࠇߟߟ޽ࠆ‫ޕ‬ ᣥ᧲ᶏ㆏ᴪ޿ߩ㓸⪭ߩ߭ߣߟߢ޽ࠆ‫ޔ‬ᗲ⍮⋵ฬฎደᏒ✛඙᦭᧻ߪ‫ߣޠ⛉᧻᦭ޟ‬๭߫ࠇࠆ⛉ࠅ↥ᬺߢᳯᚭ߆ ࠄᄢᱜᦼߦ߆ߌߡᩕ߃‫⃻ޔ‬࿷ߢ߽⋵ᜰቯᢥൻ⽷᳃ኅ㧝᫟‫ޔ‬Ꮢᜰቯᢥൻ⽷᳃ኅ㧟᫟ߥߤࠍᆎ߼ߣߒߡવ⛔⊛ᑪ ㅧ‛߇ሽ࿷ߒߡ޿ࠆ‫ో᧻᦭ޔߒ߆ߒޕ‬૕ߣߒߡߪ‫ޔ‬㊀વᑪ࿾඙ߦߪᜰቯߐࠇߡ߅ࠄߕ‫ޔ‬ᱧผ⊛ⴝਗߺߩᄌኈ ߇ㅴⴕߒߡ޿ࠆ1)‫ߩߎޕ‬໧㗴ߦኻߒߡ‫ޔ‬૑᳃⚵❱ߢ޽ࠆ‫ߩࠅߊߠߜ߹᧻᦭ޟ‬ળ‫ޔߪޠ‬Ꮢߩᱧผ߹ߜߠߊࠅផ ㅴቶ╬ߣߣ߽ߦⴝਗߺ଻ోߦะߌߚᵴേࠍⴕߞߡ޿ࠆߣߎࠈߢ޽ࠆ‫ޕ‬ ৻ᣇߢ‫ߚߒ߁ߎޔ‬ᱧผ⊛ⴝਗߺߩ଻ోߦ㓙ߒߡߪ‫ޔ‬ฦ‫ߩޘ‬વ⛔⊛ᑪㅧ‛ߩ⠴㔡ᕈ࡮㒐Ἣᕈߩ⏕଻ߣวℂ⊛ 1 −9−.
