3.2.3. Structural (Hysteretic) Damping

Try these first

1. 1.

   What is hysteretic damping?

   Hint

   Think about how materials behave under stress.

2. 2.

   How is energy dissipation represented graphically?

   Hint

   What shape do you think depicts energy loss?

3. 3.

   What determines the energy loss in hysteretic damping?

   • Material density
   • Area of the hysteresis loop
   • Velocity of the structure

   Hint

   What visual measure indicates energy dissipation?

4. 4.

   True or False: Hysteretic damping is linear in nature.

   • True
   • False

   Hint

   Consider the definition of linear versus nonlinear.

5. 5.

   Consider a building with a hysteresis loop area of 800 J. If it experiences 10 cycles of loading, what total energy is dissipated?

   Hint

   Multiply the area by the number of cycles.

6. 6.

   If a material's hysteretic damping coefficient is observed to decrease with increasing temperature, how could this impact the building design?

   Hint

   Think about how temperature changes affect material properties.
