Show hintHide hint
Think about what peak means in this context.
Question 2.
List the three performance objective categories linked to PGA.
Show hintHide hint
Remember the acronym OLC.
3Question 3.
What does PGA stand for?
- Peak Ground Analysis
- Peak Ground Acceleration
- Peak Ground Area
Show hintHide hint
Focus on the terms related to ground forces.
4Question 4.
Which performance objective is linked with a PGA of approximately 0.1g?
- Life Safety
- Collapse Prevention
- Operational
Show hintHide hint
This is the lowest threshold among the three objectives.
Question 5.
Given a structure designed for Life Safety, estimate the performance implications if it is subjected to a PGA of 0.4g.
Show hintHide hint
Reflect on what exceeding the design limit means for structural integrity.
Question 6.
Propose a method for evaluating the seismic risk of a new building using PGA and annual exceedance probabilities.
Show hintHide hint
Consider both geographic location and historical seismic activity.
