| Abstract |
This study aims to develop a box-type metal connector designed to vertically connect timber columns at the base and between stories. The
structural performance of the proposed connector was experimentally evaluated, and a simplified method for estimating its load-carrying
capacity was examined for practical design applications. A connection system was proposed in which steel tubes or round bars were inserted
into 190 × 150 mm timber columns to transfer compressive and tensile forces. Three specimens were tested under compression and three
under tension. The maximum load capacities were approximately 270 kN in compression and 90 kN in tension. The load-displacement
relationships showed stable stiffness exceeding that of larch glued-laminated timber, confirming that the developed connector can function as a
reliable structural joint. In addition, a simplified analytical model was applied to evaluate the bending moment of the steel plates,
demonstrating that the connector’s resistance can be reasonably estimated using basic analytical procedures. |
