Nonlinear Structural Instability
Author: Filippo Gazzola
This work provides a detailed and up-to-the-minute survey of the various stability problems that can affect suspension bridges. In order to deduce some experimental data and rules on the behavior of suspension bridges, a number of historical events are first described, in the course of which several questions concerning their stability naturally arise. The book then surveys conventional mathematical models for suspension bridges and suggests new nonlinear alternatives, which can potentially supply answers to some stability questions. New explanations are also provided, based on the nonlinear structural behavior of bridges. All the models and responses presented in the book employ the theory of differential equations and dynamical systems in the broader sense, demonstrating that methods from nonlinear analysis can allow us to determine the thresholds of instability.

A Tribute to Djairo Guedes de Figueiredo on the Occasion of his 80th Birthday
Author: Alexandre N. Carvalho,Bernhard Ruf,Ederson Moreira dos Santos,Sergio H. M. Soares,Thierry Cazenave
This volume of contributions pays tribute to the life and work of Djairo Guedes de Figueiredo on the occasion of his 80th birthday. The articles it contains were born out of the ICMC Summer Meeting on Differential Equations – 2014 Chapter, also dedicated to de Figueiredo and held at the Universidade de São Paulo at São Carlos, Brazil from February 3-7, 2014. The contributing authors represent a group of international experts in the field and discuss recent trends and new directions in nonlinear elliptic partial differential equations and systems. Djairo Guedes de Figueiredo has had a very active scientific career, publishing 29 monographs and over one hundred research articles. His influence on Brazilian mathematics has made him one of the pillars of the subject in that country. He had a major impact on the development of analysis, especially in its application to nonlinear elliptic partial differential equations and systems throughout the entire world. The articles collected here pay tribute to him and his legacy and are intended for graduate students and researchers in mathematics and related areas who are interested in nonlinear elliptic partial differential equations and systems.

Instabilities of fluid flows and the associated transitions between different possible flow states provide a fascinating set of problems that have attracted researchers for over a hundred years. This book addresses state-of-the-art developments in numerical techniques for computational modelling of fluid instabilities and related bifurcation structures, as well as providing comprehensive reviews of recently solved challenging problems in the field.

The need for large–scale bridges is constantly growing due to the enormous infrastructure development around the world. Since the 1970s many of them have been cable–stayed bridges. In 1975 the largest span length was 404 m, in 1995 it increased to 856 m, and today it is 1088 m. Thus the economically efficient range of cable–stayed bridges is tending to move towards even larger spans, and cable–stayed bridges are increasingly the focus of interest worldwide. This book describes the fundamentals of design analysis, fabrication and construction, in which the author refers to 250 built examples to illustrate all aspects. International or national codes and technical regulations are referred to only as examples, such as bridges that were designed to German DIN, AASHTO, British Standards, etc. The chapters on cables and erection are a major focus of this work as they represent the most important difference from other types of bridges. The examples were chosen from the bridges in which the author was personally involved, or where the consulting engineers, Leonhardt, Andrä und Partner (LAP), participated significantly. Other bridges are included for their special structural characteristics or their record span lengths. The most important design engineers are also presented.

Die dritte Auflage des Klassikers Stahlbetonbrücken behandelt in umfassender Form die Grundlagen des konzeptionellen Entwurfs sowie der Projektierung, Ausführung und Erhaltung von Brücken aus Stahl- und Spannbeton. Diese Grundlagen sind entscheidend für die Ästhetik, Tragsicherheit, Dauerhaftigkeit und Wirtschaftlichkeit einer Brücke. Mit einfachen Modellen wird ein Höchstmaß an Klarheit und Verständlichkeit erreicht. Auf Detailberechnungen wird verzichtet, da sie meist von sekundärer Bedeutung sind und weder auf die Qualität noch auf die Wirtschaftlichkeit einer Brücke einen nennenswerten Einfluss haben. Für Qualität und Dauerhaftigkeit von Stahlbetonkonstruktionen spielen die Anordnung der Bewehrung und die konstruktive Ausbildung eine entscheidende Rolle, weshalb grundsätzliche Lösungsmöglichkeiten dargestellt werden. Die Themen Entwurf, Baustoffe, Einwirkungen, Ausrüstungsteile, Schrägkabelbrücken und Erhaltung wurden grundlegend überarbeitet und erweitert.

Numerical Methods for Engineers retains the instructional techniques that have made the text so successful. Chapra and Canale's unique approach opens each part of the text with sections called "Motivation" "Mathematical Background" and "Orientation". Each part closes with an "Epilogue" containing "Trade-Offs" "Important Relationships and Formulas" and "Advanced Methods and Additional References". Much more than a summary the Epilogue deepens understanding of what has been learned and provides a peek into more advanced methods. Numerous new or revised problems are drawn from actual engineering practice. The expanded breadth of engineering disciplines covered is especially evident in these exercises which now cover such areas as biotechnology and biomedical engineering. Excellent new examples and case studies span all areas of engineering giving students a broad exposure to various fields in engineering.McGraw-Hill Education's Connect is also available as an optional add on item. Connect is the only integrated learning system that empowers students by continuously adapting to deliver precisely what they need when they need it how they need it so that class time is more effective. Connect allows the professor to assign homework quizzes and tests easily and automatically grades and records the scores of the student's work. Problems are randomized to prevent sharing of answers an may also have a "multi-step solution" which helps move the students' learning along if they experience difficulty.
