5.13.1. Basic Principle

Try these first

1. 1.

   What does the term Pseudo Spectral Acceleration refer to?

   Hint

   Think about what happens during an earthquake.

2. 2.

   What is a Response Spectrum?

   Hint

   Connect it to SDOF systems.

3. 3.

   What does a response spectrum plot?

   • Time vs. displacement
   • Peak responses vs. period
   • Energy vs. time

   Hint

   Consider what you are measuring.

4. 4.

   True or False: Spectral Velocity represents the maximum displacement of an SDOF system.

   • True
   • False

   Hint

   Think about what 'velocity' means.

5. 5.

   Given a seismic event characterized by specific ground motions, calculate the response spectrum for a target SDOF system with known mass and stiffness. Explain how the spectral values change with respect to damping.

   Hint

   Use the relationships of damping to peak acceleration and displacement.

6. 6.

   Consider an engineer tasked with using response spectra to design a new office building in a seismically active area. Detail the steps they must take, including the significance of peak response parameters.

   Hint

   Think about design processes and safety standards.
