3 cards from this section. Quick, good the night before a test.
What does Spectral Acceleration measure?
Think about how the structure reacts to an earthquake.
What is the damping ratio typically used for building design?
It's a standard value commonly referenced in codes.
What is the formula used to calculate Spectral Acceleration?
Focus on the elements involved in the seismic response.
True or False: Spectral Acceleration can be derived solely from numerical simulations.
Think about the different methods we've discussed.
Given a time history of ground motion data, apply the Newmark-beta method to calculate the Spectral Acceleration for specific periods ranging from 0.5s to 2.0s, analyzing how changes in damping ratios impact the results.
Break down into smaller time increments for clarity when using numerical methods.
Evaluate how the soil type (soft, medium, hard) influences the calculated Sa by comparing two SDOF systems subjected to identical ground motions but differing soil characteristics.
Consider the properties of each soil type and how they interact with seismic energy.
