Question 1.
What is the purpose of time-history analysis in constructing response spectra?
Show hintHide hint
Think about how structures react over time.
Question 2.
What does normalization in response spectra refer to?
Show hintHide hint
Consider how we standardize measurements.
3Question 3.
What is the primary method used for time-history analysis?
- Finite Element Method
- Newmark-Beta Method
- Response Modification Method
Show hintHide hint
Focus on numerical methods for ground motion analysis.
4Question 4.
True or False: The damping ratio increases the spectral ordinates of a response spectrum.
- True
- False
Show hintHide hint
Think about how damping affects oscillations.
Question 5.
An engineer analyzes a tall building's response spectrum using time-history analysis. The damping ratio is set at 5%, and the natural period is varied from 0.5s to 2s. Describe the observed changes in spectral ordinates.
Show hintHide hint
Think about the relationship between natural period and displacement response.
Question 6.
Construct a normalized response spectrum using a hypothetical peak ground acceleration of 0.4g and compare it to one that uses peak ground velocity of 1.2 m/s. What adjustments should be made?
Show hintHide hint
Consider how normalization relates to reference points.
