Reanalysis of Structures

This book deals with various computational procedures for multiple repeated analyses (reanalysis) of structures, and presents them in a unified approach. It meets the need for a general text covering the basic concepts and methods as well as recent developments in this area. Reanalysis is common to numerous analysis and design tasks such as nonlinear analysis, structural optimization, damage analysis, and probabilistic analysis. The book discusses various analysis models, including linear and nonlinear analysis, static and dynamic analysis, and design sensitivity analysis. It demonstrates how various concepts and methods are integrated to achieve effective solution procedures. The approach presented has several advantages in terms of generality, efficiency of the calculations, accuracy of the results and ease of implementation. Efficiency and accuracy considerations are discussed and illustrated. To clarify the presentation, many illustrative examples and numerical results are demonstrated. The text is related to a wide range of applications in such fields as Mechanical Engineering, Aerospace Engineering, Civil Engineering, and Naval Architecture. This should prove useful to students, researchers, analysts and consultants involved in analysis and design of structures. Previous books on structural analysis do not cover most of the material presented in the book.

Zusammenfassung
This book deals with multiple repeated analyses (reanalysis) of structures. Reanalysis is needed in many problems of structural analysis, design and optimization. It is related to a wide range of applications in Aerospace - gineering, Civil Engineering, Mechanical Engineering and Naval Archit- ture. The book was developed while I was teaching graduate courses on analysis, design and optimization of structures, in the United States, C- ada, Europe and Israel. It summarizes many years of research and dev- opments in these areas. The purpose of the book is to collect together the main results of this work and to present them in a unified approach. It meets the need for a general text covering the basic concepts as well as - cent developments on reanalysis of structures. This should prove useful to students, researchers, consultants and practicing engineers involved in structural analysis and design. Other books on structural analysis do not cover most of the topics presented in the book. Early developments on this subject are introduced in a previous book by the author (Design-Oriented Analysis of Structures, Kluwer Academic Publishers, Dordrecht 2002). In general, the structural response cannot be expressed explicitly in terms of the structure properties, and structural analysis involves solution of a set of simultaneous equations. Reanalysis methods are intended to analyze efficiently structures that are modified due to changes in the str- ture properties. The object is to evaluate the structural response (e. g.
