載荷速度が相欠き仕口の剛性·耐力·エネルギー吸収性能に及ぼす影響:相欠き仕口を用いた木造面格子壁の動的性状に関する研究

摘要

The wooden grid wail, the subject of this study, consists of straight timbers assembled into a grid using half-lap joints. Structural feature of the wooden grid wall is to resist extemal force by embedment of half-lap joints at grid intersection, and it is known to have generally excellent deformation performance and high toughness. The wooden grid wall is reported that the rigidity and strength vary by the number of half-lap joints. Also, it is known that the embedment of wood is affected by the loading rate. The wooden grid wail has to design using limit strength calculating method for evaluate the deformation performance. However, a study about this subject has not been reported as far as authors know. In this paper, in order to understand the influence of the loading rate and the number of half-lap joints, dynamic loading tests were performed.%本論文では，仕口数，仕口間隔，載荷速度をパラメータとして相欠き仕口の動的載荷実験を行い，構造性能について比較，考察した。また，実験結果に基づいてエネルギー吸収性能の定量的な把握を行った。本論文における試験の範囲において得られた知見を以下に示す。
