32. Response of Structures to Earthquake

Try these first

1. 1.

   What is Peak Ground Acceleration?

   Hint

   Think about what maximum means in this context.

2. 2.

   Name the two components of ground motion.

   Hint

   Consider the directions in which the ground can move.

3. 3.

   What does PGA stand for?

   • Peak Ground Area
   • Peak Ground Acceleration
   • Peak Ground Artifact

   Hint

   Think about what the 'P' in PGA represents.

4. 4.

   True or False: Structures respond in the same way to all types of loads.

   • True
   • False

   Hint

   Recall the differences between various types of loads.

5. 5.

   Given the equation of motion for an SDOF system, derive the natural frequency and explain its significance.

   Hint

   Break down the equation and consider how mass and stiffness affect frequency.

6. 6.

   Analyze how an increased damping ratio impacts the response of a structure during seismic activities.

   Hint

   Think about the relationship between damping and the structural response curves.
