摘要

In this research work, dynamic analysis of the soil-structure and filling-structure interaction effects on the nonlinear behaviour of structures is presented. It is based on the principle of elastic design taking into consideration a reduced response spectrum in terms of the ductility factor μ, which allows the validation in the non-linear domain. This method, a dynamic design procedure, uses successive approximations until getting the accuracy desired. This latest presents several advantages such as minimising the risk of errors, having a better computing time, correcting systematically errors during the iterative computation, introducing variables changes (cross-section and/ or steel section) during the design of the structure without repeating the calculation, and finally taking into account the variation of the moment of inertia in the element of the structure as well as the extension and application to other models of soil-structure interactions. The results obtained (partial moments due to rotations and displacements) using this new approach agree more or less with those resulting from recent methods.
