Challenge Problems

Push your limits with challenges.

Question 1

A three-story building exhibits three mode shapes. Each shape corresponds to different lateral displacements during seismic excitation. Describe how you can analyze these shapes to optimize the building’s design.

💡 Hint: Think about where the maximum deflections will likely occur.

Question 2

Consider a complex structure with irregular mass distribution. How would you approach determining mode shapes computationally, ensuring the accuracy of the seismic response analysis?

💡 Hint: Consider techniques that handle complexities in structures.
