5.3.2. Justification

Try these first

1. 1.

   Define lumped mass idealization in your own words.

   Hint

   Think about how you would simplify a complex system.

2. 2.

   Why is high floor stiffness important for this idealization?

   Hint

   Consider the behavior of stiff structures during dynamic loading.

3. 3.

   What is lumped mass idealization?

   • A method that distributes mass evenly
   • A simplification of mass at specific points
   • A technique that ignores mass altogether

   Hint

   Think about how we model structures in a simplified way.

4. 4.

   True or False: High floor stiffness allows for the use of lumped mass idealization.

   • True
   • False

   Hint

   Consider what high stiffness means for a building during an earthquake.

5. 5.

   Evaluate a real-world structure where lumped mass idealization could apply and justify your choice based on stiffness and design.

   Hint

   Research modern skyscrapers that are designed for seismic resilience.

6. 6.

   Design a simplified model for a multi-story building using lumped mass idealization; describe your assumptions.

   Hint

   Consider which factors to include for stiffness when creating your model.
