Question 1

What does the parameter spectral acceleration measure?

  • The speed of the ground
  • The response of structures to ground motion
  • The weight of a structure

💡 Hint: Consider how structures react during earthquakes.

Question 2

True or False: A higher damping ratio leads to a stronger perceived shaking in buildings.

  • True
  • False

💡 Hint: Think about what damping does to energy.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a building designed with a spectral acceleration factor (Sa/g) of 0.3 on a damping ratio of 5% on soft soil. Calculate the increase in spectral acceleration if the soil were to change to a stiffer type.

💡 Hint: Refer to codes that specify how soil type can factor into spectral calculations.

Question 2

A building experiences high levels of shaking during a seismic event. How would a higher damping ratio mitigate the effects on the structure compared to a lower one?

💡 Hint: Think about the concept of energy dissipation in materials.
