This paper presents a coupled finite element-boundary element approach in the time domain for the calculation of the dynamic response of structures due to dynamic excitations as arising from traffic or pile driving. The dynamic soil flexibility is calculated with a boundary element formulation in the frequency domain. It is transformed to a force-displacement relationship in the time domain and...

The paper presents an iterative procedure for the time domain deconvolution in nonlinear elastoplastic materials. approach is intended generation of input motions dynamic soil–structure interaction (DSSI) numerical analyses when desired earthquake specified at surface a soil deposit. main advantage that same constitutive model (or models) to be used DSSI simulation characterise deposit also emp...

In this paper the seismic response of linear behaving structures resting on compliant soil is addressed through application Preisach formalism to capture nonlinearities. The novel model hysteresis for nonlinear soil-structure interaction problems explored study a real structure. Through harmonic balance procedure, furthermore, simplified springs and dashpots are derived in closed form ready acc...

Practicing engineers typically follow linear methods for seismic design and assessment, confining their approach to the requirements of SANS 10160-4 (SANS 2017). This generally leads a conservative design, leaving little space apply additional tools refinement. Soil-structure interaction has beneficial effects most building structures under action. However, incorporating soil-structure in analy...
