Dynamics of Structures

NPTEL and Indian Institute of Technology Bombay via Swayam


This course will focus on characterizing the behavior of structures subject to dynamic loads (e.g., earthquake, impact, blast). Structures would be idealized to simplified single-degree-of-freedom (SDOF) and multi-degree-of-freedom (MDOF) systems. Equation of motion for SDOF systems would be developed for periodic, non-periodic and arbitrary excitations. The numerical methods to obtain the dynamic response and their limitations would be discussed. The concept of earthquake response spectrum and design spectrum will be explained and their utility in the seismic analysis and design of structures would be discussed.INTENDED AUDIENCE : B.Tech and M.Tech students .Industry professionals engaged with structural designPRE REQUISITE :Basic course in CalculusSUPPORTED INDUSTRIES : All Structural Engineering firms.Infrastructure and construction companies,CPWD,Railways,Defence sector
