In its third revised and extended edition the book offers an overview of the techniques used to solve problems in fluid mechanics on computers and describes in detail those most often used in practice. Included are advanced techniques in computational fluid dynamics, like direct and large-eddy simulation of turbulence, multigrid methods, parallel computing, moving grids, structured, block-structured and unstructured boundary-fitted grids, free surface flows. The new edition contains a new section dealing with grid quality and an extended description of discretization methods. The book also contains a great deal of practical advice for code developers and users, it is designed to be equally useful to beginners and experts.

Of all the historic train stations in London, King's Cross (1852) may perhaps be said to have the most beautiful, possibly even the purest design of them all. Two simple yet elegant steel and glass vaults "(250x22x65 m) cover the halls containing eight platforms. In the course of preparations for the 2012 Summer Olympics, John McAslan + Partners, an architectural and design practice based in London, were assigned with the redevelopment and structural extension of the station which was in dire need of major renovation.

Extensive parts of King's Cross are landmarked (Grade I-listed). In the course of two building stages, the station halls were cleaned and newly glazed, while the two Western and Eastern Range Buildings were carefully renovated and modernised.

The third stage of construction, and highlight of the building measures, is the Western Concourse with its rolling steel and glass roof. This free standing structure was newly built in front of the historic Western Range Building.

The new station entrance is located underneath a semi-circular roof that swoops up to a height of 20 m and extends with a span of 52 m and a diameter of 130 m. Aerial photographs illustrate the ideal fit of the geometry of the new roof between the rear of the Great Northern Hotel and the Western Range Building.

The largest self-supporting station roof in Europe (according to the architect) is distinguished by a white steel grid, which rises up vertically and then flares out elegantly out to the sides, much like an amazing giant cascading mushroom.

The outer rim of the roof construction weighing approximately 1,000 t rests on sixteen tree-shaped supports, each able to bear 600 t of weight.

Smart structures that contain embedded piezoelectric patches are loaded by both mechanical and electrical fields. Traditional plate and shell theories were developed to analyze structures subject to mechanical loads. However, these often fail when tasked with the evaluation of both electrical and mechanical fields and loads. In recent years more advanced models have been developed that overcome these limitations.
Plates and Shells for Smart Structures offers a complete guide and reference to smart structures under both mechanical and electrical loads, starting with the basic principles and working right up to the most advanced models. It provides an overview of classical plate and shell theories for piezoelectric elasticity and demonstrates their limitations in static and dynamic analysis with a number of example problems. This book also provides both analytical and finite element solutions, thus enabling the reader to compare strong and weak solutions to the problems.

A displacement-based method of seismic design (DBSD) is presented with particular reference to the design of reinforced concrete shear wall buildings. For preliminary design, approximate estimates of the yield and ultimate displacements are obtained, the former from simple empirical relations, and the latter to satisfy the following criteria: (1) satisfy code-specified drift limits, (2) ensure stability under P-Delta effects, and (3) keep the ductility demand within ductility capacity. For a multi-storey building the structure is converted to an equivalent single-degree-of-freedom (SDOF) system using an assumed deformation shape that is representative of the first mode. The required base shear strength of the SDOF system is determined from the inelastic demand spectrum corresponding to the ductility demand, which is the ratio of ultimate to yield displacement. The base shear is distributed across the height using an assumed pattern, such as the one given by the National Building Code of Canada, and the structure is designed for the moments produced by the estimated shears. (Abstract shortened by UMI.)
