STUDY ON A STRUCTURAL ESTIMATE OF A BOLTED JOINT FOR A WOODEN STRUCTURES : Part 1 ; Influence of loading direction for a wooden compressive strain inclined to the grain

Abstract

In the wooden single-layer space frame, the authors have been studying the influence of a bolted joint looseness, furthermore, have suggested that a bolted joint looseness should be substituted an axial and a bending rigidity in the analytical model. In this paper, judging from our several experimental studies on a bolt-wood bearing test that already been examined, the authors discussed the influence of loading direction for a wooden compressive strain inclined to the grain. In particular, as the comparison between our original experimental formulas and Hankinson formulas, the former are confirmed.
