This textbook represents our effort to make freely available to students and practitioners the theory and common applications of structural dynamics. The presentation is hoped to inspire interest and active learning. The book's content is expected to evolve and expand in time so we truly welcome suggestions from readers and colleagues. To make available in a timely manner, the first upload/edition has been limited topics that could be covered in a senior level undergraduate or an introductory level graduate course in a single semester. Given the vastness of the theory and practical details, such a compromise was inevitable. On the other hand we hope that by continuing to expand the contents at certain intervals the material will eventually cover a very significant portion of the relevant literature and current practices. This living nature of the electronic medium was what motivated us to undertake this project to begin with. We thank Northwestern University Libraries for their interest in this textbook, and we express our gratitude to Xinyan Yang for her help in solving many problems we encountered along the way.
