1.12. Resonance and Its Implications in Earthquake Engineering

Try these first

1. 1.

   Define resonance in the context of earthquake engineering.

   Hint

   Think about frequency matching.

2. 2.

   What role does damping play in resonance?

   Hint

   Consider how vibrations die down.

3. 3.

   What happens to a structure at resonance?

   • Decreased amplitude
   • Amplified oscillations
   • No effect

   Hint

   Think about the consequences of matching frequencies.

4. 4.

   True or False: All structures are equally susceptible to resonance.

   • True
   • False

   Hint

   Consider the factors that influence susceptibility.

5. 5.

   A newly constructed building registers a natural frequency of 1.5Hz. An earthquake strikes with prominent frequency content around this range. Discuss the anticipated structural response and potential recommendations for design improvements.

   Hint

   Consider the factors surrounding resonance.

6. 6.

   Evaluate the impact of inter-storey drift on a ten-story building during a seismic event experiencing resonance and recommend mitigation strategies.

   Hint

   Think about how inter-storey drift can be managed.
