Masonry testing has been undertaken using scaled models for many years. These scales.have generally been in the range 1:2 to
1:3 with smaller scales down to 1:6 being the exception. The reasons for the limited use of scale models include the low cost of the full-scale materials, the difficulty of the manufacture and instrumentation of small-scale masonry, and concerns over scaling. It is clearly appropriate to study material properties and constituent interaction at full scale but the structural performance of large panels can stretch the capabilities of even well equipped laboratories. Many masonry structural problems also involve an interaction with other materials, eg retaining walls, with self-weight being an important issue in the behaviour of both masonry and soil. This paper presents an overview of the techniques involved in small-scale masonry modelling work, the use of a centrifuge to correctly scale self-weight and opportunities for further development.
