34.8.1. When Required

Try these first

1. 1.

   Define time history analysis.

   Hint

   Think about it being like a playback of past earthquakes.

2. 2.

   What is a critical structure?

   Hint

   Where would you go right after an earthquake?

3. 3.

   What is a primary reason for conducting time history analysis?

   • To predict wind loads
   • To simulate responses to real earthquake data
   • To estimate construction costs

   Hint

   Consider what real earthquake simulations can provide for structure testing.

4. 4.

   True or False: Critical structures require less attention during seismic design.

   • True
   • False

   Hint

   Think about the role of emergency services after a disaster.

5. 5.

   Analyze the potential impact of selecting inappropriate ground motion data for a critical hospital structure located in a high seismic zone. What could be the consequences for the hospital's functionality?

   Hint

   Consider the hospital's operations and the importance of reliable functionality.

6. 6.

   A new design for an irregular shaped school building in a high seismic area is proposed, utilizing time history analysis. List potential design modifications that could enhance its seismic performance based on this analysis.

   Hint

   Think about how different elements can work together to support each other.
