Abstract

A combined finite difference-finite element with substructuring approach is proposed for solving seismically induced nonlinear soil-structure interaction problems. The substructuring is achieved by employing a super-degree-of-freedom, instead of the structure, combined with an explicit finite difference code, and the resulting interface conditions are then used as input for analyzing the structure alone with ADINA. The results demonstrate that the combined approach is efficient and economic, as compared to the pure finite element analysis.
