2 cards from this section. Quick, good the night before a test.
Define Peak Ground Acceleration (PGA).
What does 'peak' refer to in this context?
What are the three main parameters of ground motion?
Think about how ground movement can be measured.
What does PGA stand for?
What does 'peak' imply about the value?
True or False: Inelastic spectra represent structures that return to their original shapes post-load.
Think about how elastic behavior differs from inelastic behavior.
Given an accelerogram, estimate the PGA, PGV, and analyze potential structural responses based on these parameters.
Look at the highest peaks in the accelerogram data.
Design a simplified building model that can withstand specific PGV and PGA values while detailing how response spectra would inform material choices.
Use established formulas related to structural dynamics in your calculations.
