Question 1
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?
💡 Hint: Think about frequency interactions during seismic events.
Question 2
Design a hypothetical bridge using bearings and describe how they would function during an earthquake. Include the types of forces they would mitigate.
💡 Hint: Focus on the relationship between earthquake forces and structural movements.
