In regions of low and moderate seismicity, force-based models would be of little relevance in representing damage to building contents and non-structural components which are typically unrestrained and hence liable to slide, displace (with "rocking" motion) or overturn. This paper summarises findings from recent analytical and experimental investigations into the dynamic large-displacement (rocking) behaviour of freestanding objects.A simple heuristic model for predicting overturning involves the use of the elastic displacement floor spectrum. A separate model which estimates the level of shock transmitted to an object on impact with the floor is also introduced. Damage caused to the object,..
