Question 1.
What is the Response Reduction Factor?
Show hintHide hint
It reflects how much forces can be reduced due to ductility.
Question 2.
Which structural type has a higher R value, OMRF or SMRF?
Show hintHide hint
Think about which structure can handle more flexibility.
3Question 3.
What does the Response Reduction Factor (R) quantify?
- Ability to reduce seismic forces
- Cost of design
- Material strength
Show hintHide hint
Think about what the factor primarily addresses in design.
4Question 4.
True or False: Higher R values indicate better structural performance against seismic events.
- True
- False
Show hintHide hint
Remember what higher values suggest about structural systems.
Question 5.
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.
Show hintHide hint
Remember to review what critical facilities require during an earthquake.
Question 6.
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.
Show hintHide hint
Focus on how R modifies the required strength under earthquake loading.
