3.9.2. Displacement and Drift

Try these first

1. 1.

   What is the impact of higher damping on peak displacements?

   Hint

   Think about how energy dissipation works.

2. 2.

   Define inter-story drift.

   Hint

   What does it measure in tall structures?

3. 3.

   What happens to peak displacements when damping increases?

   • Increase
   • Decrease
   • Remain constant

   Hint

   Think about how energy dissipation affects movement.

4. 4.

   Higher damping results in lower inter-story drift.

   • True
   • False

   Hint

   Relate this to the mechanics of dampening.

5. 5.

   Given a tall building with a damping ratio of 0.2, estimate the peak displacement if the base displacement is measured at 0.5 meters. What implication does higher damping have on this scenario?

   Hint

   Think about how damping affects energy fluctuation.

6. 6.

   Explain how the relationship between damping and inter-story drift can be modeled in a simulation. What factors need to be accounted for?

   Hint

   Consider what aspects will change the earth's impact on floors.
