Question 1.
What does the Importance Factor (I) indicate?
Show hintHide hint
Think about why certain buildings need to be designed stronger than others.
Question 2.
What does the Response Reduction Factor (R) account for?
Show hintHide hint
Consider how a building can manage forces during an earthquake.
3Question 3.
What is the Importance Factor (I)?
- A measure of structural stiffness
- A reflection of occupancy significance
- A type of building material
Show hintHide hint
Think of buildings that are crucial during emergencies.
4Question 4.
True or False: A higher Response Reduction Factor (R) permits lower design seismic forces.
- True
- False
Show hintHide hint
Consider how energy management plays a role in design forces.
Question 5.
Given two buildings, A and B. Building A has an Importance Factor (I) of 1.2 and a Response Reduction Factor (R) of 4. Building B has an I of 1.5 and R of 3. Compare the expected seismic force if both have the same weight.
Show hintHide hint
Use the design force formula considering both I and R.
Question 6.
Discuss the pros and cons of having a high Response Reduction Factor (R). Consider its impact on safety versus cost savings.
Show hintHide hint
Think about the balance between economy and structural integrity.
