Challenge Problems
Push your limits with advanced challenges
Consider a building modeled as an SDOF system during an earthquake that experiences both base and mass excitation. Discuss how you would approach analyzing the combined influences on its motion.
💡 Hint: Think about how you would model simultaneous forces acting on the structure.
Assuming an SDOF structure has a damping ratio of 0.3, what implications does this have on its seismic performance and how would you design accordingly?
💡 Hint: Reflect on how different damping characteristics interact with seismic events.
