Question 1.
What is modal analysis?
Show hintHide hint
Think about vibrations and natural frequencies.
Question 2.
What do bearings do in bridge design?
Show hintHide hint
Consider how movement affects structures.
3Question 3.
What is the purpose of modal analysis?
- To determine structural aesthetics
- To assess bridge responses to seismic forces
- To calculate material costs
Show hintHide hint
Consider why understanding vibrations is important.
4Question 4.
True or False: Bearings are only designed for static loads.
- True
- False
Show hintHide hint
Think about what happens during an earthquake.
Question 5.
A long-span bridge undergoing modal analysis shows a natural frequency close to the dominant seismic frequency of the region. What should the engineer consider doing in the design phase?
Show hintHide hint
Think about frequency interactions during seismic events.
Question 6.
Design a hypothetical bridge using bearings and describe how they would function during an earthquake. Include the types of forces they would mitigate.
Show hintHide hint
Focus on the relationship between earthquake forces and structural movements.
