27.8. Use of Seismograms in Earthquake Engineering

Try these first

1. 1.

   What does a seismogram record?

   Hint

   Think about what changes during an earthquake.

2. 2.

   Why is liquefaction important to consider?

   Hint

   What happens to soil when it's shaken in a saturated condition?

3. 3.

   What is the primary use of seismograms in earthquake engineering?

   • Record seismic waves
   • Establish building codes
   • Predict weather effects

   Hint

   Focus on what seismograms are designed to capture.

4. 4.

   True or False: Liquefaction only occurs in dry soil.

   • True
   • False

   Hint

   Consider the conditions under which liquefaction occurs.

5. 5.

   Given a specific seismogram, how would you analyze it to assess structural safety during an earthquake? Include considerations of soil type.

   Hint

   Examine historical data for similar soil conditions and building types.

6. 6.

   Discuss the implications of using nonlinear models in seismic design compared to linear models in regard to safety standards.

   Hint

   Consider the limitations of predicting outcomes in materials under stress.
