30.8. Software and Practical Applications

Try these first

1. 1.

   What does spectral acceleration (Sa) represent?

   Hint

   Think about how a structure reacts to shaking.

2. 2.

   Name two software applications used for seismic analysis.

   Hint

   Consider popular structural analysis tools.

3. 3.

   What is spectral acceleration (Sa)?

   • Maximum acceleration during an earthquake
   • Average ground motion
   • Total seismic weight of a structure

   Hint

   Think about how buildings respond to seismic waves.

4. 4.

   True or False: CQC stands for Cut Quadratic Combination.

   • True
   • False

   Hint

   Recollect the term's correct naming convention.

5. 5.

   Consider a modal analysis of a 15-story building with irregular shape. What factors must be included to accurately calculate the spectral acceleration, and why?

   Hint

   Recall the variables that influence how buildings sway.

6. 6.

   How would using a higher spectral acceleration value change the design requirements for a building in a high seismic zone compared to a low seismic zone?

   Hint

   Think about how structural codes adjust for varying risk levels.
