| Outline of Final Research Achievements |
Drift pinned connection consists of steel plate, circular steel bar, and timber with slit and hole. that is one of the popular connection for glulam or sawn timber structure. WhichIn this research, The structural design method of drift pinned connection for CLT was developed. Initial stiffness, yield load, ultimate load under the tensile load and shear load was derived for the CLT panel connection. Derived equations were confirmed by the moment resisting tests and shear tests of the connections

| Academic Significance and Societal Importance of the Research Achievements |
中層大規模木構造の普及に従い、汎用的なCLTパネル端部の接合部設計法の整備が急務となっている。本研究は、扱いやすい形で、汎用的な CLTパネル端部の接合部設計法を提案するという意味で、社会的意義の大きい研究である。木質構造の設計者だけでなく、一般的な構造の設計者に設計法を利用してもらうことで、CLTの普及につながると考えられる。
