Different glueline thicknesses pull-out behaviour of mengkulang glulam
Tengku Anita Raja Hussin1, Oon, Vincent2, Rohana Hassan3.
Timber connection is still facing inadequacy of engineering studies. Mechanical and
adhesive joints are the two main types of connections being used for timber connection. In
this study, pull-out strength test is carried to determine the best glue line thickness and the
failure modes occur. Three different glue-line thicknesses of 2mm, 3mm and 4mm was
tested with holes thicknesses of 14mm, 16mm and 18mm respectively were drilled on 9 with
3 specimens of each thickness. This test is carried out until failure in the specimen by using
the Universal Testing Machine with load capacity of 1000kN and at the rate of 2mm/min.
Phenol-resorcinol-formaldehyde (PRF) is the adhesive used for the strengthening purposes
with ratio of PRF hardener and resin of 1:5 was used in this experiment. The dowel glued-in
steel dowel is 10 mm in diameter from S 235 steel type. For the results; The data shows that
glue line thickness of 2mm does generate the highest maximum load compared to 3mm
and 4mm of glue line thickness with the value of 2.394kN compared to 2.223kN and
1.789kN respectively. However, glue line thickness of 3mm shows highest breaking load of
1.714kN compared to 1.631kN of 2mm glue line thickness and 1.454kN of 4mm glue line
thickness. Therefore, it is proven that the 2mm glue line thickness is more superior in strength
and shear stress than 3mm and 4mm of glue line thickness.
