Abstract
Traditionally, joints in timber structures are made with solid
steel fasteners. With those of dowel type form and diameter
above that of nails and small bolts, joint failure is likely to
occur in the timber components. It was thought that this
problem could be reduced by replacing solid steel dowels
with those of a hollow form and that by varying the wall
thickness, a chosen combination of strength and stiffness
could be attained. In this paper, experimental work based on
a series of tests on single dowel joints is presented. A finite
element model was developed and verified and with the
validated model, parametric studies of joints with various
dowel wall thicknesses were undertaken to investigate the
potential of such an idea.
