2 cards from this section. Quick, good the night before a test.
What does spectral acceleration (Sa/g) measure?
Think about structures and shocks from earthquakes.
Why is a damping ratio of 5% typically used in designs?
Consider the purpose of having a consistent measure.
What does the parameter spectral acceleration measure?
Consider how structures react during earthquakes.
True or False: A higher damping ratio leads to a stronger perceived shaking in buildings.
Think about what damping does to energy.
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.
Refer to codes that specify how soil type can factor into spectral calculations.
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?
Think about the concept of energy dissipation in materials.
