Show hintHide hint
Think about how a structure moves when it vibrates.
Question 2.
Why are mode shapes important?
Show hintHide hint
Consider their role during earthquakes.
3Question 3.
What does a mode shape describe?

Show hintHide hint
Consider if they can interfere with each other.
Question 5.
A multi-storey building has a fundamental mode shape showing significant sway at its natural frequency. Explain how this affects its seismic design.
Show hintHide hint
Consider the dynamics between built structures and earthquake frequencies.
Question 6.
Analyze how a bridge reacts differently to varying load distributions in its mode shapes during an earthquake.
Show hintHide hint
Think about how tension and compression alter the structural responses.
