a two-degrees-of-freedom sway frame structure with space for the installation of an adjustable damper on its upper floor. The walls of the structure were slotted tightly into the floors to ensure a high degree of fixity throughout testing. A schematic illustration outlining the dimensions of the structure and an image of the constructed model are shown in Fig. 1(a) and (b). Centrifuge tests were conducted at 50 g, meaning that the model structure with
the inclusion of its base foundation resembles a prototype structure of 7.5 m in height. However, no pre-existing or design prototype structure was borne in mind for the design of the
small-scale centrifuge model. Instead, the model was used to study the effects of different parameters on a general multipledegrees-of-freedom sway frame structure.
