•Static Nonlinear Analysis technique, also known as
sequential yield analysis, or simply
"push-over" analysis has gained significant popularity during the past few years.
•It is one of the three analysis techniques recommended
by FEMA 273/274 and a main component of the
Spectrum Capacity Analysis method
(ATC-40).
•Proper application can provide valuable insights into
the expected performance of structural
systems and components
•Misuse can lead to an erroneous understanding of the
performance characteristics.
•Unfortunately, many engineers are unaware of the subtle
details that have to observed in order
to obtain useful results from such analysis.
•This presentation is an attempt to identify the most
important considerations necessary for a
push-over analysis to provide meaningful
results.
