5 cards from this section. Quick, good the night before a test.
What is the definition of seismic excitation?
Think about what happens to buildings during earthquakes.
Which equation represents seismic excitation?
Remember the components of mass, damping, and stiffness.
What does the term 'seismic excitation' refer to?
Focus on the effects on buildings during earthquakes.
True or False: Damping is important for minimizing vibrations in structures during earthquakes.
Reflect on the function of damping during dynamic loads.
Given a building with a mass of 5000 kg, damping of 200 Ns/m, and stiffness of 40000 N/m, calculate the natural frequency of the building.
Use the natural frequency formula derived from the stiffness and mass.
Discuss the impact of ignoring damping in a seismic design for a building located in a high seismic activity area.
Think about what damping does to oscillations and how that affects safety.
