== Abstract ==

Bonded brickwork loadbearing walls are commonly seen in many colonial period
structures around the world; however, most research studies in the past and the current
design provisions are primarily based on single leaf brickwork. Due to the anisotropic natu re
of brickwork, the strength and deformation characteristics would be different for bonded
brickwork walls and their design using the provisions of single leaf bonded brickworks may
be un-conservative. Therefore, to understand the compressive behaviour of differently bonded
brickworks, an experimental programme followed by a numerical investigation were carried
out in this research. The experimental programme comprised of testing nine wallettes under
uniaxial compression. Three different types of bonded thicknesses (single, double and triple)
were used to construct the wallettes. The experimental results are presented and discussed in
terms of failure modes, compressive strengths and stress-strain responses obtained. Further a
numerical investigation based on the micro modelling approach was employed to verify the
experimental findings. The experimental and numerical modelling results indicate that the
change in brickwork thicknesses does not significantly increase the compressive strength of
the masonry. The increased number of weak perpend joints in the bonded brickwork wallettes,
could be a reason of lower strength and thus, a general notion of increment in compressive
resistance due to the reduction in slenderness i s not applicable for bonded brickwork.
Parametric analyses were also carried out and reported for different slenderness ratios to
extend the understanding on the behaviour of bonded brickworks under compression.
