19.7.4. Response Spectrum

Try these first

1. 1.

   What is a Response Spectrum?

   Hint

   Think about what engineers might need to know during an earthquake.

2. 2.

   Why is the Response Spectrum important?

   Hint

   Consider how buildings are affected during seismic events.

3. 3.

   What does the Response Spectrum plot display?

   • Ground motion duration
   • Peak response of SDOF systems
   • Magnitude of an earthquake

   Hint

   Focus on what is essential for engineers.

4. 4.

   True or False: The Response Spectrum is not useful in designing buildings for earthquakes.

   • True
   • False

   Hint

   Think about the implications of seismic design.

5. 5.

   Given a Response Spectrum of a region prone to earthquakes, determine how you might adjust the building design specifications for a high-rise versus a low-rise building.

   Hint

   Consider which buildings are more affected by lower versus higher frequencies.

6. 6.

   Design a structural element based on a given Response Spectrum. Specify the materials and justification based on its expected seismic performance.

   Hint

   Think about which materials would perform well under stress.
