| Summary: | Connections of timber structures using concealed bonded-in rods offer a solution
to the efficient joining methods. However, the importance of certain basic joint
characteristics, and the influence of moisture content are not yet fully understood.
This paper describes a comprehensive experimental and numerical investigation
into the fundamental material and joint geometry characteristics of rods bonded
in to timber. The treatment type and level of moisture content both considered,
along with test configuration that included rod and timber species. It was found
that epoxy adhesives out-performed all other types investigated, and pull-out
strengths can be significantly improved by indicating suitable moisture content
and treatment. Moisture content at higher level sample exhibited higher pull-out
strength. This indicates that the shear strength values of the tested specimens
were affected by the moisture content and same result when tested with different
type of treatment. There is a strong correlation between the moisture content of
the wood, type of treatment and mean shear strength. Failure mode in moisture
content and type of treatment is related to the anatomical properties of the wood
that influences the wettability of adhesive used. |
