Question 1

What does the equation mu¨(t)+cu˙(t)+ku(t)=-mu¨_g(t) represent?

  • The behavior of an SDOF system during static load
  • The ground motion effects on an SDOF system
  • The natural frequencies of a structure

💡 Hint: Focus on what happens during seismic events.

Question 2

Relative displacement is defined as?

💡 Hint: Think about one part moving differently compared to another.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
