樹木の枝分かれモデルに基づく木組フレーム接合　その1：構造システムとT字接合部の曲げ性能

抄録

This paper aims to evaluate the design and bending performance of a wood-only timber frame joint inspired by the growth model in trees. The stem branch junction’s features were explored and approached in a simplified application of glued-laminated column-beam members joined in a conical mortise-tenon with bent laminated veneer plies flowing seamlessly across their interface. The joint was manufactured in Japanese Cedar with Beech bent plies, tested, and compared to glued-in rod (GIR) and lag screw bolt (LSB) joints; it showed comparable efficiency in moment transfer with reasonable failure patterns compared to conventional joint systems with added-steel accessories.^Note1)
