3D FEM ANALYSIS OF EMBEDDED BEHAVIOR OF WOOD (PART 1): STIFFNESS EVALUATION OF ELASTIC EMBEDDED BEHAVIOR (ONE-WAY EXTRA LENGTH)

Timber structural joints should be modeled as semi-rigid joints reflecting local deformation. Therefore, this study aims to contribute to a theoretical formulation of its behavior, and deals with one of its dominant factors, embedded behavior, especially elastic embedded behavior due to equally displacement. Currently, the Inayama model is often used to evaluate a stiffness of the behavior, but the model approaches only geometrically and lacks mechanical knowledge of the behavior. So, this study uses 3D FEM analysis to clarify the mechanical mechanism, and makes a mechanical model. However, for simplicity, this paper deals with the case on one-way extra length.
