鋼板挿入式ボルト·ドリフトピン接合部における荷重－すべり特性の評価法

摘要

筆者らはこれまでに木－木ボルト2面せん断接合における荷重変形 特性を，終局に至るまで統一的に評価する手法を提案した。本報で は同様の手法を鋼板挿入式接合に適用し，接合部の終局に至るまでの 挙動を推定する手法を提案する。%Timber joints composed with a single bolt or drift pin and steel inserted plate were studied. Polynomial approximation conducted by the assumption of the theory of a beam on the elastic foundation gave the initial slip modulous, proportional limit, and Yield load in the more plactical manner than tthat of the currently used design method and furthermore, secondary slip modulous caused by the Rope Effect was conducted in the closed form. This design method was conpared with the experimental results and showed good agreements. We hope the poposed method help the engineers and architects design the timber buildings and structure more easily and safely.
