Question 1.
What is a performance point?
Show hintHide hint
Think about how much a structure can handle versus what it needs to withstand.
Question 2.
Describe what a capacity spectrum shows.
Show hintHide hint
Visualize this as a graph of curve interactions.
3Question 3.
What defines the performance point in seismic design?
- The maximum height of a structure
- The intersection of demand and capacity curves
- The weight of the building
Show hintHide hint
It relates to how much demand a structure can withstand.
4Question 4.
True or False: The capacity spectrum shows how much capacity a structure can have without any external loads.
- True
- False
Show hintHide hint
Think about what loads affect the capacity spectrum.
Question 5.
A building demonstrates high elasticity but poor damping and faces a seismic event. Analyze the impact on its capacity spectrum and performance point.
Show hintHide hint
Reflect on how elasticity and damping interact during seismic activity.
Question 6.
Design a hypothetical structure and sketch its capacity spectrum. Indicate the performance point and discuss potential design improvements.
Show hintHide hint
Use principles of structural engineering to conceptualize enhancements.
