Question 1.
What does the Response Reduction Factor (R) represent?
Show hintHide hint
Think about how structures react to seismic forces.
Question 2.
Is a higher R value better for a building's seismic design?
Show hintHide hint
Recall the values associated with different structural systems.
3Question 3.
What does a higher Response Reduction Factor (R) indicate?
- Lower ability to absorb forces
- Higher ability to absorb forces
- No impact on design
Show hintHide hint
Think about what ductility means in terms of seismic resistance.
4Question 4.
True or False: An ordinary RC moment frame has an R value of 5.
- True
- False
Show hintHide hint
Recall the table of R values presented.
Question 5.
Design a small three-story building using a barycentric braced frame system for a seismic zone with an R value of 4. Discuss how you would approach calculation of seismic forces.
Show hintHide hint
Pay attention to how the R value influences overall forces.
Question 6.
Analyze how choosing an R value of 3 versus 5 affects material costs in a high-seismic area. Discuss using examples.
Show hintHide hint
Consider reinforcement type and quantity.
