Fundamentals of Earthquake Vibrations of buildings
Static load v/s Dynamic load (force control and displacement control), simplified single degree of freedom system, modeling of buildings, natural frequency, resonance v/s increased response, responses of buildings to different types of vibrations like free and forced, damped and undamped vibration, response of building to earthquake ground motion, introduction to multi degree of freedom systems (mode shapes).



Earthquake Basics
Earth interior, plate tectonics, faults, consequences of earthquake, Earthquake parameters, magnitude & intensity, scales, Seismic zones of India, damages caused during past earthquakes (world wide).
