A domain decomposition approach for coupled modelling of nonlinear soil-structure interaction

Interdisciplinary research in computational mechanics engaging Structures and Geotechnics Sections, recognising that advanced modelling has evolved separately in two sub-disciplines. Novel general method proposed for coupling any nonlinear structural and geotechnical solvers, enabling consideration of nonlinearity in structure and soil, as necessary for example under seismic loading. Benefits of new coupling method demonstrated through successful coupling of ADAPTIC and ICFEP, two advanced in-house programs which provide computational backbone for applied engineering research in Structures and Geotechnics at Imperial, and which have been employed on soil-structure interaction research projects, e.g. “Using Blinding as Struts in Cut and Cover Excavations” (EPSRC EP/D505488/1).
