Question 1

Describe how you would analyze a 10-story asymmetric building located in a seismically active area. Consider its modal properties and the coupling effects in your approach.

💡 Hint: Think about what steps would ensure you capture both translational and rotational behaviors.

Question 2

Given a structure shows significant torsional amplification during an earthquake, suggest design modifications to improve its resilience.

💡 Hint: Consider how structural changes can redirect forces.
