3.7.2. Empirical Formulas

Try these first

1. 1.

   What does DMF stand for?

   Hint

   Consider what could affect damper adjustments in seismic design.

2. 2.

   Name one effect of increasing damping in seismic design.

   Hint

   Think about how adjustments in damping levels could influence structural safety.

3. 3.

   What is the primary purpose of Damping Modification Factors?

   • To increase design forces
   • To adjust spectral responses
   • To reduce material usage

   Hint

   Think about the function it serves in seismic design.

4. 4.

   True or False: A higher damping ratio will generally lead to increased spectral demand.

   • True
   • False

   Hint

   Consider how damping impacts the forces experienced during seismic activity.

5. 5.

   Design a small-scale building that incorporates damping modifications. Discuss how varying damping percentages can affect the material and structuring decisions.

   Hint

   Reflect on how adjustments to damping can lead to different structural choices and engineering priorities.

6. 6.

   Analyze the potential impact on seismic design efficiency if all structures used a standardized DMF rather than empirically defined factors. Discuss pros and cons.

   Hint

   Think of the balance between safety and efficiency in engineering practices.
