Show hintHide hint
Think about its role in seismic design.
Question 2.
Why is damping important in seismic design?
Show hintHide hint
Refer to its effects on structural safety.
3Question 3.
What does DMF stand for?
- Demand Modification Factor
- Damping Modification Factor
- Design Modification Factor
Show hintHide hint
Focus on its relation to damping.
4Question 4.
True or False: DMFs are only applicable to structures with standard damping ratios.
- True
- False
Show hintHide hint
Remember their primary function.
Question 5.
A building has an assumed damping of 5%. Calculate the adjusted spectral acceleration if the real damping is found to be 8%. What is the DMF used?
Show hintHide hint
Make sure you substitute the right values into the formula.
Question 6.
Discuss the potential impacts on structural design if a damping ratio is underestimated during initial calculations.
Show hintHide hint
Reflect on safety margins and unexpected stress.
