The work reported in this paper illustrates our conviction that the route to more effective design of structure / foundation systems is through better cooperation between structural and geotechnical specialists. To this end we demonstrate the use of an existing dynamic structural analysis package in modelling the earthquake response of framed structures on shallow foundations. The work presented in this paper is a continuation of that in Wotherspoon et al. [1]. The buildings analysed are multistorey reinforced concrete framed structures founded on discrete shallow footings, connected with tie beams (not part of the foundation). Yielding and uplift characteristics of the foundations have been modelled by adapting available structural models in the software. The underlying soil is stiff clay.
