Structural Dynamics

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.
