Question 1.
What does the demand spectrum represent?
Show hintHide hint
Think about the forces expected during seismic activity.
Question 2.
What is indicated by the capacity curve?
Show hintHide hint
Consider what the structure can endure.
3Question 3.
What does the intersection of the demand spectrum and capacity curve indicate?
- Structural failure
- Performance point
- Seismic hazard
Show hintHide hint
Think about what that point represents in terms of safety.
4Question 4.
True or False: The demand spectrum can change over time based on new seismic data.
- True
- False
Show hintHide hint
What happens when new information arises?
Question 5.
Given historical seismic data, construct a demand spectrum and then compare it with a capacity curve for a new multi-story building design. Discuss the adjustments needed based on where they intersect.
Show hintHide hint
Refer to the seismic data and building codes.
Question 6.
Discuss the implications of having a performance point significantly above the capacity curve. How does this influence design and safety considerations?
Show hintHide hint
Consider both structural integrity and regulatory requirements.
