Re: Pushover Analysis Techniques

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Remember, Push over analysis is a 1960's era estimated hand analysis
technique with a stated list of limitations and simplifing assumptions. 
Similar to the approximate methods of the portal and cantilever methods for
frame analysis, push over requires the structures to be of shear response
modes or greatest participation from the first mode and not a flexural
response.

Computational push over analysis has been proposed for non-linear material
analysis of first mode, shear mode, dynamic response analysis.  This
disregards any higher modes and any interstory movement differences and
contributions.

If you think you want to use this method, review the original literature
from the 60's and 70's for the assumptions and limitations.
