Question 1.
What is the definition of seismic excitation?
Show hintHide hint
Think about what happens to buildings when the ground shakes.
Question 2.
Define relative displacement in the context of SDOF systems.
Show hintHide hint
It's a way to compare two positions.
3Question 3.
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
Show hintHide hint
Focus on what happens during seismic events.
4Question 4.
Relative displacement is defined as?
Show hintHide hint
Think about one part moving differently compared to another.
Question 5.
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.
Show hintHide hint
Subtract the motion of the ground from the mass's displacement.
Question 6.
Evaluate how changing the damping ratio of an SDOF system affects its response during seismic events. Provide a comparative analysis with examples.
Show hintHide hint
Consider real-life structures deeply with higher damping ratios and their benefits.
