A nonlinear HHT-? method with elasticplastic soilstructure interaction in a coupled SBFEM/FEM approach
This article presents a new method for the calculation of elasticplastic building ground deformations and elasticplastic building ground failure including wave propagation in the ground. The presented procedure is a hybrid method, based on several common calculation methods. Included is a nonlinear calculation with the finite element method (FEM), a nonlinear HHT-alpha method with full NewtonRaphson iteration and the scaled boundary finite element method (SBFEM). The presented method can be used as a tool for the accurate calculation of building ground deformations and the stability of the subsoil with included dynamic loading.
