This book covers a wide range of edited papers in the areas of fluid mechanics presented at the Seventh International Conference on Advances in Fluid Mechanics held at The New Forest, UK in May 2008. The conference emphasizes the advancement of knowledge in fluid mechanics problems with new applications. The basic mathematical formulations and their solutions by analytical and numerical methods, are discussed together with the experimental work.This papers in this book are presented under the following topics: Convection, Heat and Mass Transfer; Experimental versus Simulation Methods; Computational Methods in Fluid Mechanics; Multiphase Flows; Boundary Layer Flows; Hydraulics and Hydrodynamics; Wave Studies; Industrial Applications; Biofluids; Turbulence Flow; Environmental Fluid Mechanics; and Fluid Structure Interactions

Soil–structure interaction in tall buildings by a discrete force method
Author: A. Nadjai, BEng, MSc, PhD, MIStructE, MIABSE, PGCUT, D. Johnson, BEng, MSc, PhD, MICE, FIStructE, and J. F. Lyness, BSc, MSc, PhD, MICE, FIStructE, AFIMA | Size: 0.22 MB | Format:PDF | Quality:Unspecified
The importance of base flexibility on the elasto-plastic behaviour of spatial shear walls subjected to any type of loading was examined. An analysis of elasto-plastic spatial shear walls was developed using a discrete force method, which models the shear walls as a system of interconnected discrete structural elements and the base flexibility by effective rotational and vertical elastic stiffnesses Kb and Kv, respectively. As the magnitudes of these stiffnesses depend on the properties of the supporting soil and also on the characteristics of the foundation itself, different soils were considered. The analysis was based on the force approach, using as redundants the shear forces, not only at the contraflexural points of the connecting beams, but also at wall junctions. The elasto-plastic condition was restricted to the connecting beams by using a convenient bilinear model for the force formulation. The objective was to provide a theoretical treatment of the foundation–structure interaction that is suitable for implementation in the discrete force method. In addition, the results obtained in the discrete force modelling of the soil interaction are presented, and the applicability of the model to some representative problems is discussed.

This paper deals with the response of building clusters during earthquakes,
their effect on the ground motion, and how individual buildings interact with the
soil and with each other. We simulate the ground motion during the 1994
Northridge earthquake and focus on the coupled response of multiple simplified
building models located within the San Fernando Valley. Numerical results show
that the soil-structure interaction (SSI) effects vary with the number and dynamic
properties of the buildings, their separation, and the impedance with respect to the
soil. These effects appear as: (i) an increased spatial variability of the ground
motion; and (ii) significant reductions in the buildings' base motion at high
frequencies, changes in the higher natural frequencies of the building-foundation
systems and variations in the average roof drift, with respect to those of the
corresponding rigid-base and isolated SSI models.
