Question 1.
What does IDA stand for?
Show hintHide hint
Think about the first letters of each word.
Question 2.
Why do engineers use IDA?
Show hintHide hint
What can we learn from different earthquake magnitudes?
3Question 3.
What is the primary purpose of Incremental Dynamic Analysis (IDA)?
- To assess structural aesthetics
- To evaluate seismic performance
- To optimize material cost
Show hintHide hint
Think about the area of engineering concerned with earthquakes.
4Question 4.
True or False: IDA can help identify the performance of a structure at various seismic intensities.
- True
- False
Show hintHide hint
Reflect on what IDA assesses.
Question 5.
You are tasked with analyzing a 10-story building using IDA. Assume you apply scaled seismic motions and notice that it begins failing at a scale of 1.5. What design changes would you recommend to prevent failure?
Show hintHide hint
Think about what aspects of the structure would be weakest under increased load.
Question 6.
Develop a theoretical framework for using IDA to assess an existing building against retrofitting options. What analysis steps are necessary?
Show hintHide hint
Focus on the sequence of actions required for analysis.
