This chapter deals with introduction to structural dynamics and its application to offshore structures. Basics of single-degree of freedom are discussed to highlight the conventional mathematical model of single-degree of freedom. Free vibration analysis and forced vibration analysis are discussed with focus on few important dynamic characteristics of the single and multi-degrees of freedom models. Solved numerical examples of determining natural frequencies and mode shapes of different mathematical model of single and multi-degrees of freedom systems are included.
