Question 1.
What does the Capacity Curve represent?
Show hintHide hint
Think about what happens to a structure during seismic events.
Question 2.
Define stiffness degradation in simple terms.
Show hintHide hint
How does a structure behave under stress?
3Question 3.
What does the Capacity Curve represent?
- A. The cost of construction
- B. Shear force vs. top displacement
- C. The height of the building
Show hintHide hint
Imagine what happens to buildings during earthquakes.
4Question 4.
True or False: Stiffness degradation improves a structure's performance during seismic events.
- True
- False
Show hintHide hint
Consider the definition of stiffness degradation.
Question 5.
Given a structure with a known base shear capacity of 200 kN and a observed top displacement of 10 cm, calculate the new base shear capacity if the stiffness degrades leading to a 30% reduction in capacity.
Show hintHide hint
Consider how reducing stiffness affects overall capacity.
Question 6.
Analyze a scenario where retrofitting a building adds shear walls, improving its capacity measured by a performance point increase from 300 kN to 400 kN. Discuss implications for seismic design.
Show hintHide hint
Referring back to how performance points interact with design principles will help.
