The book is an excellent text as well as a practical reference for civil, mechanical and aerospace engineers. It has been identified as a work that is admirable in its lucidity and complete in itself, in the sense that it contains virtually all the material that an engineer who wishes to become skilled in dynamic analysis is likely to need. The book provides comprehensive coverage of the analytical tools required to determine the dynamic response of structures. The topics covered include: formulation of the equations of motion for single- as well as multiple-degrees-of-freedom discrete systems using the principles of both vector mechanics and analytical mechanics; free vibration response; determination of frequencies and mode shapes; forced vibration response to harmonic and general forcing functions; dynamic analysis of continuous systems; wave propagation analysis; finite element analysis, component mode synthesis, and analysis of nlinear systems. A unique feature of the text is its special emphasis on the application of numerical methods in the analysis of discrete systems. It provides a comprehensive coverage of both the traditional and state-of-the-art numerical techniques of response analysis, such as analysis by numerical integration of the equations of motion and analysis through frequency domain. A large number of solved examples and exercise problems add to clarity and reader comprehension. The third edition builds on the success of its predecessors and enhances the emphasis on numerical techniques. Thus, significantly expanded coverage is provided of the finite element method and numerical integration of nlinear equations of motion, which are w covered in separate chapters devoted to them. An entirely new chapter has been added on component mode synthesis, a technique that is suitable for the analysis of very large systems. The book is suitable as a text for one- or two-semester courses at the senior undergraduate level and graduate level in engineering. The book is organized so as to follow the logical steps in the analysis. Thus the formulation of the equations of motion for both single- and multi-degree-of-freedom systems is presented prior to the techniques for the solution of such equations. However, by appropriate selection of chapters to be covered it is possible to study the single-degree-of-freedom systems from formulation of the equations of motion to their solution prior to studying similar topics for multi-degree-of-freedom systems. A solution manual will be of considerable benefit to teachers offering courses in structural dynamics.
Dr. Jag Mohan Humar, is currently Distinguished Research Professor of Civil Engineering at Carleton University, Ottawa, Canada. Dr. Humar obtained his Ph.D. from Carleton University in 1974. He joined Carleton as a faculty member in the Department of Civil Engineering in 1975 and became a full professor in 1983, and served as the Chairman of the Department of Civil and Environmental Engineering from 1989 to 2000. Dr. Humar's main research interest is in structural dynamics and earthquake engineering. He has published over 120 journal and conference papers in this and related areas. He is also the author of a book entitled Dynamics of Structures, published by Prentice Hall, USA in 1990. The second edition of the book has been published by Balkema Publishers of Netherlands in 2002. In February 2000 Dr. Humar led a Canadian Scientific mission to Gujarat to study the damage caused by the Bhuj earthquake. Dr. Humar is actively involved in the development of seismic design provisions of the National Building Code of Canada. Over the last 15 years he has served as a member of the Standing Committee on Earthquake Design, an advisory body to National Building Code of Canada (NBCC) for its seismic design provisions. During these years the NBCC seismic provisions have undergone substantial revisions, and many of the changes and new requirements have been influenced by Dr. Humar's work in the field. Along with teaching, academic administration, and research, Dr. Humar has also been active in engineering consulting He served as a special consultant for several outstanding civil engineering projects, including the National Aviation Museum in Ottawa and the SkyDome in Toronto. He was a seismic design consultant on several other projects, which include the Earthquake Response Study of the Alexandria Bridge across the Ottawa River, Seismic Rehabilitation of the Victoria Museum, Ottawa, Blast Load Analysis of the Mackenzie Tower, Parliamentary Precinct, Ottawa. He also served as a member and chair of the experts panel to review the seismic rehabilitation and upgrade of the West Block, Parliamentary Precinct, Ottawa. Dr. Humar has received several awards for his outstanding contributions to teaching, research, engineering practice, and the profession. Dr. Humar serves as a field referee for many international journals including the ASCE Journals of Structures and Engineering Mechanics, the Journal of Sound and Vibration, the Journal of Structural Dynamics and Earthquake Engineering, and the Canadian Journal of Civil Engineering. For 7 years he served as an Associate Editor for the Canadian Journal of Civil Engineering. Currently he is the Associate Editor of the International Journal of Earthquake Engineering and Structural Dynamics.
