Question 1

What does the Response Reduction Factor (R) quantify?

  • Ability to reduce seismic forces
  • Cost of design
  • Material strength

💡 Hint: Think about what the factor primarily addresses in design.

Question 2

True or False: Higher R values indicate better structural performance against seismic events.

  • True
  • False

💡 Hint: Remember what higher values suggest about structural systems.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a new design for a 10-story hospital in a seismic zone where it needs a higher importance classification. Discuss at least two factors to consider when choosing the Response Reduction Factor.

💡 Hint: Remember to review what critical facilities require during an earthquake.

Question 2

Suppose an OMRF building is in Zone IV and allocated an importance factor of 1.5. Calculate the effective seismic reduction for the structure if the design requires a response reduction factor of 3.

💡 Hint: Focus on how R modifies the required strength under earthquake loading.
