33.1.1. Single-Degree-of-Freedom (SDOF) System Response

Try these first

1. 1.

   What does SDOF stand for?

   Hint

   It's a term used in structural dynamics.

2. 2.

   What is the primary purpose of a response spectrum?

   Hint

   Think about how it helps engineers assess structural performance.

3. 3.

   What does the variable 'm' in the SDOF governing equation represent?

   • Mass
   • Damping
   • Frequency

   Hint

   Think about what it means for an object to resist acceleration.

4. 4.

   True or False: The response spectrum helps in assessing how structures perform during earthquake events.

   • True
   • False

   Hint

   Recall its main applications in seismic design.

5. 5.

   Determine the natural period of a system with a mass of 20 kg and stiffness of 500 N/m.

   Hint

   Use the natural period formula and apply the given values.

6. 6.

   Assess how a damping ratio of 10% would affect the response spectrum of a given structure.

   Hint

   Think about how damping influences oscillation decay and its effect on structural responses.
