Question 1.
What is dynamic analysis?
Show hintHide hint
Think about how structures react during earthquakes.
Question 2.
Define seismic stoppers.
Show hintHide hint
They are similar to shock absorbers.
3Question 3.
What is the purpose of modal analysis in bridge design?
- To predict static loads
- To analyze dynamic response
- To calculate material costs
Show hintHide hint
Focus on how bridges react during seismic events.
4Question 4.
True or False: Seismic stoppers are not necessary in bridge design.
- True
- False
Show hintHide hint
Consider what happens to structures without these devices.
Question 5.
Design a hypothetical bridge that incorporates dynamic analysis, detailing the specific types of dampers and their arrangement.
Show hintHide hint
Consider where the bearings would go and what types of dampers might best suit the design.
Question 6.
Assess the seismic design of an existing bridge. Identify its strengths and weaknesses regarding seismic restraints.
Show hintHide hint
Look into how the bridge was designed to respond to different seismic zones.
