4.11.2. Response Spectrum Analysis

Try these first

1. 1.

   What is Response Spectrum Analysis?

   Hint

   Think about how engineers ensure safety against earthquakes.

2. 2.

   What does SDOF stand for?

   Hint

   Consider how we simplify structures for analysis.

3. 3.

   What does Response Spectrum typically illustrate?

   • Maximum temperature
   • Maximum structural response
   • Maximum wind speed

   Hint

   Think about what aspect of structures during events we are trying to analyze.

4. 4.

   True or False: RSA only applies to Multi Degree of Freedom systems.

   • True
   • False

   Hint

   Remember the definition of SDOF.

5. 5.

   A 15-story building is modeled as an SDOF system with a natural frequency of 2 Hz. If a seismic event has a frequency of 2 Hz as well, what phenomenon would occur and what design considerations should be employed?

   Hint

   Think back to how a swing moves more when pushed at the same frequency.

6. 6.

   Using given response spectrum data, calculate the expected maximum acceleration for a building with a period of 0.5 seconds. The response spectrum data shows a peak acceleration of 1.2g at that period. What does this mean for the design?

   Hint

   Consider how g relates to forces experienced by the building.
