Question 1.
What is a Response Spectrum?
Show hintHide hint
Think about how structures respond to seismic forces.
Question 2.
What does SRSS stand for?
Show hintHide hint
It's a method for combining modal responses.
3Question 3.
What is the purpose of the Response Spectrum Method?
- To analyze static load
- To evaluate dynamic load responses
- To define material properties
Show hintHide hint
Think of earthquake impacts on structures.
4Question 4.
CQC is typically used for what type of analysis?
- True
- False
Show hintHide hint
Consider the relationship between modal frequencies.
Question 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.
Show hintHide hint
Reflect on how close frequencies can influence modal interactions.
Question 6.
Evaluate how the Response Spectrum Method would change if a building’s damping ratio increases from 2% to 10%. Discuss the implications.
Show hintHide hint
Think about how damping influences seismic response calculations.
