It begins with the derivation of the basic equations of motion for an ideal single degree-of-freedom structure using various approaches, and the solution of these equations for different types of loading, with the emphasis on the physical behaviour of the structure to different types of loads to establish simplified methods of analysis. And then, it discusses the numerical methods for response analysis and earthquake response of structures. This naturally then leads to development of equations for multi-degree-of-freedom structures, with multi?storied buildings as the example structures, and free and forced vibration response analysis of these multi?storied buildings. Finally, a simplified analysis of MDOF systems using the concept of generalized single degree?of?freedom systems and the dynamics of continuous systems are introduced. (from nptel.ac.in)
