Analysis of Structures An Integration of Classical and Modern Methods Harry H. West Presents a true integration of the classical and modern methods of structural analysis. The classical formulations are used to develop fundamental concepts of analysis, and many of these approaches are cast into matrix format to illustrate some of the characteristics of matrix methods. After sufficient generalization, modern matrix methods are then presented. This dual approach enables students to understand and employ the modern computer methods of structural analysis as well as use the classical methods to solve small problems with confidence and check isolated portions of computer results. 1980 Matrix Structural Analysis William McGuire and Richard H. Gallagher A rigorous, well-organized book that examines computer-oriented structural analysis, with a strong emphasis on current applications. The book features coverage of both framed structures (trusses, beams, plane and space frames) and continuous structures (plates and shells). The authors define the terminology, coordinate systems and fundamental concepts and procedures of computerized structural analysis, laying the foundation for more advanced treatments, such as finite element analysis. Includes many worked out examples. Fully SI metric. 1979 Concepts and Applications of Finite Element Analysis, Second Edition Robert D. Cook This introduction to the finite element method for graduate students in applied mechanics and civil and mechanical engineering stresses the physical and practical aspects of structural mechanics. It covers coordinate transformation, structural dynamics, nonlinear problems, errors and convergence, proper computer use, heat transfer problems, and weighted residual methods. The new edition has been extensively revised to include new material on computer use and misuse, conduction heat transfer, and weighted residual methods. In addition, more numerical examples and homework problems have been added. 1981
Synopsis
From theory and fundamentals to the latest advances in computational and experimental modal analysis, this is the definitive, updated reference on structural dynamics.
This edition updates Professor Craig's classic introduction to structural dynamics, which has been an invaluable resource for practicing engineers and a textbook for undergraduate and graduate courses in vibrations and/or structural dynamics. Along with comprehensive coverage of structural dynamics fundamentals, finite-elementbased computational methods, and dynamic testing methods, this Second Edition includes new and expanded coverage of computational methods, as well as introductions to more advanced topics, including experimental modal analysis and "active structures." With a systematic approach, it presents solution techniques that apply to various engineering disciplines. It discusses single degree-of-freedom (SDOF) systems, multiple degrees-of-freedom (MDOF) systems, and continuous systems in depth; and includes numeric evaluation of modes and frequency of MDOF systems; direct integration methods for dynamic response of SDOF systems and MDOF systems; and component mode synthesis.
Numerous illustrative examples help engineers apply the techniques and methods to challenges they face in the real world. MATLAB® is extensively used throughout the book, and many of the .m-files are made available on the book's Web site. Fundamentals of Structural Dynamics, Second Edition is an indispensable reference and "refresher course" for engineering professionals; and a textbook for seniors or graduate students in mechanical engineering, civil engineering, engineering mechanics, or aerospace engineering.
Synopsis
Provides the basic material needed to use structural dynamics computer programs and to do structural dynamics testing. Introduces the numerical techniques underlying finite element computer codes through use of ``hand solutions and the coding of several subroutines in FORTRAN and BASIC. Emphasizes the mathematical modelling of structures and the methods for solving structural dynamics problems with a digital computer. Presents solution techniques applicable to various engineering disciplines.
Synopsis
While retaining much material covered in classical texts on structural dynamics and vibrations, this text emphasizes the mathematical modelling of structures and the methods for solving structural dynamics problems with a digital computer. Using a systematic approach, it thoroughly reviews the basic principles of structural dynamics, presenting solution techniques that apply to various engineering disciplines. The book specifically features:
- An extensive introduction to numerical techniques for computing natural frequencies and mode shapes and for computing transient response
- A systematic introduction to the use of finite elements in structural dynamics analysis
- An application of complex frequency response representations for the response of single and multiple-degree-of-freedom systems
- A complete exposition of both the mode-displacement and mode-acceleration versions of mode-superposition for computing dynamic response
- An introduction to practical methods of component mode synthesis for dynamic analysis
- An introduction of an instructional matrix manipulation and finite element computer code, ISMIS (interactive Structures and Matrix Interpretive System) for solving structural dynamics problems.
Civil, aerospace and mechanical engineers will find the book amply illustrated with numerous worked-out examples tailored to their specific fields. Upon completion of the book they will be able to read and apply the technical literature on this topic, and use structural dynamics computer programs intelligently.
