Question 1.
What is natural frequency?
Show hintHide hint
Think about how things naturally move.
Question 2.
What does damping do to a vibrating system?
Show hintHide hint
How do you slow a swing down?
3Question 3.
What is the purpose of using Duhamel's Integral?
- To analyze free vibrations
- To calculate forced vibrations
- To determine damping ratios
Show hintHide hint
Focus on the type of vibration being analyzed.
4Question 4.
True or False: Elastic response spectra are used for structures undergoing plastic deformation.
- True
- False
Show hintHide hint
Think about how structures behave under stress.
Question 5.
An SDOF system has a natural frequency of 3 Hz, and its damping ratio is 0.05. If it experiences earthquake ground motion with a peak acceleration of 2g, calculate the expected peak response using the response spectrum.
Show hintHide hint
Use appropriate response spectrum formulas based on the provided values.
Question 6.
A building designed as an SDOF system is found to exhibit inelastic behavior during an earthquake. Discuss the implications of this on the design spectrum and propose design alterations.
Show hintHide hint
Think about how construction might need to adapt to changing dynamics.
