Primarily, two models are commonly used to describe rocking of rigid bodies; the Housner model, and the Winkler foundation model. The first deals with the motion of a rigid block rocking about its base corners on a rigid foundation. The second deals with the motion of a rigid block rocking and bouncing on a flexible foundation of distributed linear springs and dashpots (Winkler foundation). The...

This paper aims to study the influence of soil-structure interaction on plastic energy demand spectra directly derived from the energy-balance equations of soil-shallow-foundation structure with respect to an ensemble of far-field strong ground motions obtained from Pacific Earthquake Engineering Research (PEER) database and recorded on alluvium soil. The superstructure is modeled as a single-d...

This research presents the impact of base fixity on seismic analysis including soil-structure interaction (SSI) considering linear and nonlinear soil-foundation interface conditions. A set of inelastic time history analyses using a yielding singledegree-of-freedom structural system with different fixity conditions at the base are used. The base fixity configurations considered are: 1) fixed-bas...

Abstract This paper deals with statistical and modeling uncertainty on the estimation of long-term extrapolated extreme responses in a monopile offshore wind turbine. The is addressed by studying effect simulation length. Modeling explored evaluating effects considering rigid flexible foundation. soil's flexibility taken into account improved apparent fixity method. To identify most relevant en...

Software development means the development of a wide range of work products covering different views on a system. These views are generally represented using different notations. In this paper we propose a model for the static part of a software development process that enables an integrated foundation of work products on the basis of a system model, as well as a flexible foundation of notation...
