6 sample questions

Question 1.
What are natural frequencies?
Show hintHide hint
Think about the natural oscillation of an object.
Question 2.
Define base shear.
Show hintHide hint
Remember how buildings respond to earthquakes.
3Question 3.
What does the term 'base shear' refer to?
- Lateral force at the base of structures
- Vertical load on the structure
- Total mass of the building
Show hintHide hint
Think about the forces acting during an earthquake.
4Question 4.
'Natural frequencies are essential in designing structures for which reason?'
- True
- False
Show hintHide hint
Consider how structures behave under vibration.
Question 5.
Design a structural model for an 8-story building using MDOF principles, considering modal responses to earthquake forces and outlining how to estimate base shear from these modes.
Show hintHide hint
Use modal participation factors for a more accurate representation.
Question 6.
Evaluate the seismic performance of a specific high-rise building using modal analysis and time-history data from prior earthquakes. How would you ensure safety and resilience?
Show hintHide hint
Remember to use effective mass calculations to justify your design choices.
