| description | Connections for timber structures using concealed bonded-in rods offer one
possible solution to the development of more efficient joining methods.
However the importance of certain basic joint characteristics, and the
influence of adhesive type and properties, are not yet fully understood and as
such design criteria are lacking. This paper describes a comprehensive
experimental and numerical investigation into the fundamental material and
joint geometry characteristics of rods bonded in to timber. The adhesive type
and performance are both considered, along with test configuration and joint
parameters 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 through careful selection and optimization of
the joint geometry. Balau sample exhibited higher pull-out strength with a
means of 10.43 MPa (τta) and 15.65 MPa (τra). This indicates that the shear
strength values of the tested specimens were affected by the density of wood
species although the results indicate a declining value of average shear
strength due to the adhesive type. There is a strong correlation between the
density of the wood and mean shear strength. Failure mode in softwood and
hardwood is mostly related to the anatomical properties of the wood which
influences the wettability of adhesive that has been use. |
