Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Use the design force formula considering both I and R.

Question 2

Discuss the pros and cons of having a high Response Reduction Factor (R). Consider its impact on safety versus cost savings.

💡 Hint: Think about the balance between economy and structural integrity.
