14.16.1. Case Study: Mexico City Earthquake (1985)

Try these first

1. 1.

   What is resonance?

   Hint

   Think about what happens when you push a swing.

2. 2.

   Define natural frequency.

   Hint

   Consider the frequency of a guitar string when plucked.

3. 3.

   What occurs when the natural frequency of a building matches the frequency of seismic forces?

   • Increased stability
   • Resonance
   • Structural fortification

   Hint

   Think about how a swing moves with timing from a push.

4. 4.

   True or False: Soft soils can amplify seismic waves.

   • True
   • False

   Hint

   Focus on soil characteristics under stress.

5. 5.

   Design a hypothetical mid-rise building in Mexico City considering its natural frequency and site conditions. Explain your considerations regarding the soil type and the design measures you would implement.

   Hint

   Think about both the mass and stiffness in your design choices.

6. 6.

   Evaluate the long-term societal impacts of the 1985 Mexico City earthquake on local architecture and urban planning.

   Hint

   Consider both the architectural style and regulatory changes.
