| Summary: | A study was conducted with the objective of gathering
information on the strength and stiffness properties and
behaviour of joints in rattan furniture subjected to various
kinds of load. Four types of joint commonly found in rattan
furniture making industry, i.e., nailed (N), nailed and bound
with rattan rope (N+B), screwed (S), and screwed and bound
(S+B) were tested in with drawal, lateral and bending loads.
The results showed that in generals crewed joints were
stronger and stiffer than nailed joints. Furthermore, although
bindings have increased the joint strength, the bindings have
not improved the joint stiffness against the all types of
load, except the side bending load. Regression analyses showed
that the rattan specific gravity has significantly influenced the withdrawal and later all strength. The results of the
analyses have also provided some in sights especially on how
the nails, screws or bindings were contributing to the
strength and stiffness properties of the joints. Through this
knowledge, theoretical models were developed for predicting
the bending and side bending rotational stiffnesses of the
joints. In the first model, the bending stiffness was
proportional to the withdrawal stiffness of joint. The second
model showed that the side bending stiffness was much
determined by the bending properties (El) of the embedded
fasteners. Beside its predictive functions, the thearetical
models were envisaged to be a basis for future efforts to
develop better rattan jointing methods. |
