Challenge Problems
Push your limits with advanced challenges
Consider a 2-story building modeled as a single-degree-of-freedom system. Calculate the relative displacement if the top mass experiences a displacement of 0.1m when the ground moves 0.05m.
💡 Hint: Subtract the motion of the ground from the mass's displacement.
Evaluate how changing the damping ratio of an SDOF system affects its response during seismic events. Provide a comparative analysis with examples.
💡 Hint: Consider real-life structures deeply with higher damping ratios and their benefits.
