| Abstract | Each joint in a timber structure is critical to support the load capacity of structural members. The current Malaysian Standard for designing timber structures is MS: 544 (2001). However, information for withdrawal capacity of wood dowel in MS: 544 for Part 2 (Permissible Stress Design of Solid Timber) and Part 5 (Timber Joints) is insufficient as it does not provide the withdrawal properties of the timber connection system. Therefore, this research is aimed to evaluate the optimum withdrawal performance of different selected embedded lengths of wood dowel for the Merbau species. The common standard test method for withdrawal capacity of timber fasteners is used to determine the withdrawal capacity of wood dowel by inserting dowel into the timber. Four different lengths were selected for this study, i.e., 30 mm, 60 mm, 90 mm, and 120 mm with a constant dowel diameter of 16 mm. As for the results, the observation on the average ultimate load-carrying capacities of each group of the embedded length was reported. From the test, the withdrawal capacity that had been recorded by embedded lengths of 30 mm, 60 mm, 90 mm, and 120 mm were 1234.75N, 2619.90N, 3128.80N, and 3963.96N, respectively. Whilst, withdrawal resistance based on the sequence of the embedded length were 41.46 N/mm, 43.66 N/mm, 34.76 N/mm, and 33.03 N/mm, accordingly. |
