Editorial: embedded foundations under complex loading

On behalf of my co-editors I would like to welcome you to this themed issue of Géotechnique based around the performance of foundations under complex loading. The call for papers was inspired by the increasing interest in modern infrastructure developments that face a challenging loading environment. Examples include the installation of large numbers of wind turbines (both onshore and offshore) and the demand for fully earthquake-resistant foundations, where Géotechnique has already published many contributions on these topics. These challenges have led to new research and innovative design solutions concerning the accurate prediction and modelling of capacity, stiffness and dynamic behaviour of foundations. Piles and caissons of unprecedented size are being contemplated and new installation technologies are being developed to safely sustain large, multi-component and often cyclic loads. These must be resisted while meeting long-term static and dynamic foundation performance requirements set by challenging structural specifications in harsh environments, such as for offshore wind developments. If you are interested in these themes you may like to have a look at other previous and current publications in Géotechnique such as those by Bienen et al. (2018), Liu et al. (2019), Lovera et al. (2020), Richards et al. (2019), Truong et al. (2019) and Zografou et al. (2019).
