Challenge Problems
Push your limits with advanced challenges
A multi-story building has been modeled with 12 DOFs. If during a seismic analysis it was found that the first two modes account for 80% of the response, is it reasonable to consider it a single-degree-of-freedom system for certain analyses? Justify your answer.
💡 Hint: Consider the concept of mass participation in SDOF.
Explain the impact of ignoring rotational degrees of freedom in an asymmetric structure during seismic analysis.
💡 Hint: Think about how torsion complements translation in buildings.
