Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a two-story building modeled as an MDOF system, compute the mass, damping, and stiffness matrices. Then indicate how you would use modal transformation for your calculations.

💡 Hint: Start by clearly defining the mass and stiffness parameters for each floor.

Challenge 2 Hard

Discuss the implications of non-orthogonal modes in a practical engineering scenario. What effects might this have on analysis?

💡 Hint: Consider what happens when modes interfere with one another.
