Question 1.
What happens to natural frequency when mass is added to a structure?
Show hintHide hint
Consider the relationship between mass and frequency.
Question 2.
Define the soft storey effect.
Show hintHide hint
Think about how strength varies within a structure.
3Question 3.
What is the effect of adding mass to a structure?
- Increases natural frequency

Show hintHide hint
Consider the physics of mass and frequency.
4Question 4.
True or False: Weak stiffness can make a structure more vulnerable in seismic events.
- True
- False
Show hintHide hint
Think about structural integrity in vibrations.
Question 5.
Analyze a scenario where a high-rise building with uneven mass distribution is subjected to an earthquake. Discuss potential failures and suggest design improvements.
Show hintHide hint
Consider the relationship between structure design and earthquake impacts.
Question 6.
Calculate the impact of changing boundary conditions on a specific structure's natural frequency. How would it differ if changed from fixed to pinned?
Show hintHide hint
Reflect on how the constraints influence frequency calculations.
