The response of a wooden house during earthquakes is not necessarily estimated by static characteristics of house. This paper describes the evaluation of torsional response based on vibration table test of three dimentional frames induced translational and diagonal direction. The main results are as follows. Torsional response induced by vibration of diagonal direction is larger than that of translational direction. Amplification coefficient of stress based on time-domain response analysis is

This paper describes the evaluation of torsional response based on vibration table test of three dimentional frames induced translational and diagonal direction. The main results are as follows. Torsional response induced by vibration of diagonal direction is larger than that of translational direction. Ampli� cation coef� cient of stress based on time-domain response analysis is larger than corrected torsional coef� cient or shape coef� cient based on static characteristics. ࡣࡌ ࠉᆅႸ࠾ࡅᮌఫᏯࡢࡡࡌᛂµࡣᚲࡎࡋწຊᏛⓗ≉ᛶ ࡔࡅ࡛ࡣো౯࡛ࡁ࡞࠸ࠋࡇࡢ⌮⏤ࡋ࡚ᘓ≀ࡢწⓗ๛ᚰᆅ Ⴘ࠾ࡅᐇၯࡢືⓗࡡࡌ୰ᚰࡀ୍Ҥࡋ࡞࠸ࡇ 1), 2) ᩳ ධᑕࡢᘓ≀ᛂµ≉ᛶࡢಀࡀͳ៖ࡉ࡚࠸࡞࠸ࡇ࡞ࡀͳ࠼ ࠋᚑࡗ࡚⌧যওἲ࠾ࡅࡡࡌࣥṇಀᩘ࠶࠸ࡣᙧ ≧ಀᩘ Fe ࡡࡌো౯ࡣືⓗো౯ࡣ࡞ࡗ࡚࠸࡞࠸ࠋ ࠉࡇࡇ࡛ࡣ୍స೫ᚰ༢ᒙᮌWయᯫᵓࡢದ᪉ྥධᑕᩳධᑕ ࡢᛂµ≉ᛶືྎᐇቲॾᯒȆᯝᇶ࡙ࡁ᳨খࡋᩳධᑕ ࡢᙳᅚࡘ࠸᳨࡚খࡍࠋࡇࡢၯࡡࡌᛂµࡢືⓗࡡࡌ୰ᚰ ᛂຊቑศಀᩘ╔┠ࡍࠋ 2. ᐇቲᴫो 2.1ࠉቲయᴫोࠉቲయᴫोᅗ 1 ♧ࡍࠋసǼᑍἲࡣԪࠎ࡛▷ದ᪉ ྥ 1820mm࿇ದ᪉ྥ 2730mmၥࡣ 2730mm ࡛࠶ࠋ᩿ჳᑍἲ࣭ᮦ ✀ࡣᰕ࠾ࡧᅵྎ 105mm ॵࡢࢫࢠᱱ 105mm180mm ࡢ ࢶͿຊቨཌࡉ 9mm ࡢᵓ⏝ྜᯈࢶࡋࡓࠋࡇࡢ࠺ ᑠࡉ࡞ቲయࡢሙྜᬑ೫Ϳຊቨᕤࡋࡓࡢ࡛ࡣ๛ᛶࡀഓ࡞ Ϳຊቨප̘ࡢച࠸ࡀࡡࡌᛂµࡢച࠸ࡉ࡞࠸ࠋࡑࡇ࡛ ๛ᛶపࡃᢚ࠼ࡓͿຊቨࡢ᭷ࡏ࠸ 2100mm ࡋตᡴࡕ N50@300 ࡋࡓᅗᜠཧ↷ ࠋ᥋ྜൺࡣ▷ࡒᕪ࣭ࡕȵࡂຍᕤࡋ ᰕᱱ᥋ྜൺ͊Ꮚᯈࣝࢺ M12ᰕО HD ฐ≀࠾ࡧ࣮ࣥࣝ ࢺ M16 ࡛ࣷ JIG ɝȆࡋࡓࠋᗋࡣ๛ᗋࡍࡓᵓ⏝ྜᯈ ࢶ24mm ⏝ࡋตࡣ N70@150 ࡋࡓࠋ֤ฌࡣ 600N/m 2 600 (2.73 1.82)=2980N Ѝ 300kg ࡋ ࢭ࣓ࣥࢺࢴᆒ¬ප̘ࡋࡓࠋ ຍࡣ Y ᪉ྥࡋྛቲయࡢͿຊቨප̘ᅗ 3 ࡑࡒࡢ࣓ࣛ ࣮ࢱࢢ 1 ♧ࡍࠋ೫ᚰࡣ X ᪉ྥࡢࡢ 1 స೫ᚰ࡛ྛቲయࡢ೫ᚰ ⋡ࡣ0.12 ᝬ 0.37 ࡛࠶ࠋࡇࡢ೫ᚰ⋡ቲయྡࡋ࡚࠸ࠋ ᏱᐑᏛᕤᏛ◊"⛉ ᩍᤵ ᕤ༤
