dc.description.abstract | ABSTRACT: In the past decade, there has been an increased focus on the environmental impacts of construction and a movement
towards more sustainable construction products. Timber is one such sustainable product that can achieve these environmental
targets but, while timber has a high strength-to-weight ratio parallel to the grain, it demonstrates poor strength perpendicular to
the grain. As a result, stress perpendicular to the grain is an important factor in the design of timber structures, especially in areas
of concentrated loading, such as supports. This paper describes a study, which examines the use of compressed wood dowels as a
sustainable alternative to the self-tapping steel screws for reinforcement against perpendicular to the grain compressive stresses.
Glued laminated timber specimens were reinforced with 2, 4 and 6 dowels using the same arrangement and dimensions as outlined
in Eurocode 5 for self-tapping steel screws. The results show a significant improvement in both load-bearing capacity and stiffness.
When compared to the unreinforced condition, the results showed an increase in load-carrying capacity of up to 30% for the 6
dowels arrangement. An increase in stiffness of up to 36% for 6 dowels arrangement was also observed. Additionally, good
agreement was found when comparing the experimental results to design equations adapted from recently proposed Eurocode 5
recommendations for compression reinforcement using self-tapping steel screws. | en_IE |
