'Structural Dynamics and Seismic Design' is a course offered in B. Tech. in Civil Engineering program at School of Engineering, Amrita Vishwa Vidyapeetham.

Unit 1

Introduction to structural dynamics – importance of structural dynamics - types and sources of dynamic loads - distinguishing features of a dynamic problem – methodology for dynamic analysis – types of structural vibration - basic terminology.

Single Degree of Freedom: Linear systems: Equation of motion - components of vibration system - natural frequency - viscous damping - response to undamped and damped free and forced vibration - response to support motion – principle of accelerometers and displacement meters.

Unit 2

Two Degrees of Freedom: Equations of motion - Eigen value problem - free vibration response – forced vibration response to harmonic excitation - response to support motion - modal analysis.

Earthquake Resistant Design: Elements of Engineering Seismology - Indian Seismicity – faults – seismic waves – earthquake intensity and magnitude – earthquake ground motion - behaviour of structures in the past Earthquakes – basic terminology.

Earthquake Response: Linear systems: Earthquake ground motion – response spectrum - response history analysis
