32.1.1. Nature of Earthquake Ground Motion

Try these first

1. 1.

   What are the two main components of ground motion?

   Hint

   Think about the directions in which forces can act.

2. 2.

   What is an accelerogram?

   Hint

   It is a type of data collected during an earthquake.

3. 3.

   What does ground motion result from?

   • Tectonic plate movement
   • Seismic waves
   • Wind forces

   Hint

   Consider how energy is released during an earthquake.

4. 4.

   True or False: The vertical component of ground motion is usually more critical than the horizontal components.

   • True
   • False

   Hint

   Reflect on which forces buildings are designed primarily to resist.

5. 5.

   A building in an earthquake-prone area experiences severe horizontal ground motion. Explain how engineers might design the building to mitigate potential damage due to this motion.

   Hint

   Reflect on different techniques commonly used in earthquake-resistant design.

6. 6.

   Consider a scenario where both horizontal and vertical components affect a building. Describe how the structure might need to adapt to accommodate both types of motion.

   Hint

   Think about how different forces might interact and affect structural integrity.
