Challenge Problems
Push your limits with advanced challenges
Analyze a scenario where a building of different heights is subjected to seismic loading. Discuss how many modes you would consider and why.
💡 Hint: Consider the effective mass participation factors.
If a structure is modeled with 10 modes, but only 6 effectively contribute to the seismic response, calculate the participation factor.
💡 Hint: Think about percentages and effective mass participation.
