It is widely believed that soil-structure interaction (SSI) can improve a building's ability to withstand earthquakes. However, recent earthquakes and studies have highlighted the disastrous consequences of ignoring SSI effects, causing conflicting opinions on its impact on the seismic behaviour. As a result, some contemporary design codes choose to ignore SSI or only consider its beneficial effects. Moreover, previous research has mainly focused on low or mid-rise moment frames, and impacts of SSI on commonly used structural systems of high-rise buildings have received little attention.In this study, a soil-foundation-structure model based on finite element software was employed to examine SSI effects on high-rise buildings. The validity of the model was confirmed through shaking table tests. The study explores a range of superstructure and substructure parameters to compare the seismic response of rigidly and flexibly supported structures. Moreover, beneficial and detrimental scenarios concerning SSI were identified, and code-based procedures that offer a secure and cost-effective structural design approach were developed.The study demonstrates that compared to structures modeled with a rigid base, those modeled with a flexible base that incorporates SSI effects exhibit amplified lateral deflections and inter-storey drifts to varying degrees. While piled foundations can mitigate the foundation rocking, the displacement response of piled foundation models may not necessarily be smaller than that of compensated foundation models. Blindly increasing the rigidity of the foundation and subsoil without considering SSI effects may not improve structural safety or economic efficiency.Furthermore, the study found that SSI can significantly increase the base shear for both piled foundation structures and classical compensated foundation structures supported by Ce soil. In contrast, SSI has a beneficial effect on classical compensated foundation structures supported by De and Ee soil types, as it reduces the base shear. In terms of the displacement response, SSI generally increases the inter-storey drifts for almost all cases examined, which has a negative impact on the high-rise buildings. When the subsoil exhibits sufficient stiffness, the amplification coefficient for base shear is nearly equivalent to the amplification coefficient for inter-storey drifts after considering SSI. In contrast, as the soil stiffness decays, inter-storey drifts are amplified, and the base shear is reduced.Finally, based on these findings, code-based procedures were developed to provide a safe and economical structural design method. Designers can easily determine the base shear of high-rise flexible base structures without conducting laborious numerical computations during the design process.
