7.18. Role in Seismic Design Codes

Try these first

1. 1.

   What are seismic design codes?

   Hint

   Think about the safety measures for buildings.

2. 2.

   Define natural period.

   Hint

   What does 'cycle' refer to in vibration?

3. 3.

   What is the primary purpose of seismic design codes?

   • To maximize aesthetic appeal
   • To ensure structural safety
   • To minimize construction costs

   Hint

   Think about what’s most important during an earthquake.

4. 4.

   True or False: Importance factors consider the type of occupancy of a building.

   • True
   • False

   Hint

   Recall which buildings need to function post-earthquake.

5. 5.

   Given a new code introduces a higher base shear for buildings in seismic zones, discuss potential implications on construction costs and design considerations.

   Hint

   Consider how safety might outweigh costs in earthquake-prone areas.

6. 6.

   In a specific region, buildings with a natural period of 1 second are found to perform poorly in earthquakes. Propose modifications in the design or code that could enhance their performance.

   Hint

   Think about strategies to avoid resonance.
