Supporting footings of lightweight buildings on reactive soils are susceptible to damage induced by the cyclic shrink-swell movement of the ground, causing extensive financial damage. Due to this issue and limitations of existing analytical methods, the main aim of this study is to investigate the interaction between shrink-swell soils and raft footings (i.e., stiffened rafts and waffle pod rafts), by performing parametric simulations using a simplified three-dimensional hydro-mechanical finite element model. The developed model considers the link between soil saturation, soil suction and volumetric soil strain. Stiffened rafts and waffle pod rafts were observed to interact differently with ..
