What is the first step in the idealization of a structure?
Think about how the structure will move during an earthquake.
Where do we typically lump the mass for most structures?
Consider where the greatest forces apply during seismic events.
What is the primary purpose of idealizing a structure as SDOF?
Recall why we want to make our analysis simpler.
True or False: We only consider lateral movements in SDOF systems.
Think about what types of displacements are included.
Given a 10-story building with uniform mass distribution, describe how you would approach the idealization process for seismic analysis.
Step through each idealization step.
A building's seismic analysis shows high sensitivity to stiffness changes. Discuss how you would adjust the idealization process in this case.
Think about how structural adjustments affect your model.
