Structural Dynamics

Structural Dynamics. Instructor: Prof. Ramancharla Pradeep Kumar, Department of Earthquake Engineering Research Centre, IIT Hyderabad. This course will study the effect of dynamic loads on structures, how structures behave, and what is the response of the structures. Topics covered in this course include: Dynamic equilibrium equation of structures; Response of a single degree of freedom system to dynamic excitation: free vibration, harmonic loads, pulses and earthquakes; Generation response spectra; Response of multi-degree of freedom systems; Vibration control technique; Dynamic behaviour of non-structural element.
