4 cards from this section. Quick, good the night before a test.
What is the natural frequency range for low-rise buildings?
Consider the number of stories.
Define resonance in the context of earthquake engineering.
Think about matching frequencies.
What is the typical natural frequency range for high-rise buildings?
Think about the building height.
Resonance occurs when the frequency of earthquake waves matches a building's natural frequency.
Reflect on the implications of matching frequencies.
A new low-rise building experiences an earthquake with a dominant frequency of 5 Hz. If the natural frequency of the structure is 5 Hz, what considerations should engineers keep in mind regarding resonance?
Consider strategies to mitigate resonant effects.
Assess a situation in which a medium-rise building encounters an earthquake with frequencies predominantly between 1-3 Hz. What structural adaptations can significantly lower the risk of resonance?
Think about additional mechanisms to absorb shocks.
