Abstract
Understanding the structural behaviour of the drystone Iron-age brochs is essential for their investigation and conservation, but their chaotic collapse patterns have been studied in a fragmentary manner primarily as historic evidence by archaeologists. The response of brochs to structural action was simulated by building two scale models and testing them in settlement, a possible source of failure. With the key features carefully reproduced and overall identical dimensions, the effect of variation of basal style between ground-galleried and solid-based, the two main types, was examined. The tests indicated that solid-based brochs can withstand a horizontal disp...
