This book discusses the conceptual theory of structural dynamics, using simplified methods and clear, concise explanations. It illustrates all the hypotheses in a simple and effective way and describes in detail the derivation of all related formulations. Further, comprehensive step-by-step explanations combined with conceptual derivations, drawings and figures allow readers to grasp all the analytical formulations related to the dynamics of structures. Covering free and forced vibrations of single- and multi-degree of freedom systems represented as structure, subjected to dynamic load, the book also explores the most common types of dynamic loads applicable to structures, such as harmonic loads, impact loads and earthquakes, presenting relevant details, derivations and effective problems to explain the concept for various conditions. In addition, each chapter provides examples at different levels to help students, researchers and engineers gain a better understanding of thetopics better, and includes numerous real-world problems to familiarize readers with the challenges related to structural engineering.

Farzad Hejazi is an Associate Professor and Research Coordinator at the Department of Civil Engineering, Faculty of Engineering, University Putra Malaysia (UPM), where he has also been an innovation champion since 2013 and a member of the Housing Research Center's management committee. He received his Ph.D. in Structural Engineering from the University Putra Malaysia in 2011 and worked as a postdoctoral fellow until 2012. In addition, he teaches Ph.D. students in structural engineering fields such as the finite element method, structural dynamics, advanced solid mechanics, advanced structural analysis and earthquake resistance structure. He manages and supervises a research team consisting of 20 Ph.D. students and 8 master's students, which is involved in various high impact research and industry projects funded by the Ministry of Higher Education Malaysia, Ministry of Science, Technology and Innovation, PlaTCOM Venture Malaysian Government Agency, University Putra Malaysia and industrial companies and has led to 15 patents being filed in the USA, Japan, Germany, Canada, New Zealand and Malaysia. Four of his patents are related to vibration dissipation devices already licensed to industry for mass production and implemented in various construction projects, such as bridges and other structures.

Tan Kar Chun holds a first-class honors degree in Civil Engineering from the University Putra Malaysia (UPM), and is currently pursuing his Ph.D. in Structural Engineering at UPM. He has been a consultant in the civil and structural engineering industry for the past five years, and during that time he has been involved in multiple projects at various scales: from a 1,400-acre township development to a 50-storey high-rise building.
