33.10.2. Response Spectrum Method (Linear Dynamic Analysis)

Try these first

1. 1.

   What is a Response Spectrum?

   Hint

   Think about how structures respond to seismic forces.

2. 2.

   What does SRSS stand for?

   Hint

   It's a method for combining modal responses.

3. 3.

   What is the purpose of the Response Spectrum Method?

   • To analyze static load
   • To evaluate dynamic load responses
   • To define material properties

   Hint

   Think of earthquake impacts on structures.

4. 4.

   CQC is typically used for what type of analysis?

   • True
   • False

   Hint

   Consider the relationship between modal frequencies.

5. 5.

   Consider a high-rise building with a fundamental frequency of 1 Hz. If the second mode frequency is 1.5 Hz, discuss whether to use SRSS or CQC for seismic response calculations.

   Hint

   Reflect on how close frequencies can influence modal interactions.

6. 6.

   Evaluate how the Response Spectrum Method would change if a building’s damping ratio increases from 2% to 10%. Discuss the implications.

   Hint

   Think about how damping influences seismic response calculations.
