displacement; (b) Results of push-over analysis (after Archer, 2001)

The push-over method is expected to provide information on many response
characteristics, which cannot be obtained from an elastic static or dynamic analysis
(Krawinkler and Seneviratna, 1998); they are:
-

Identification of the critical regions where the deformation demands are expected
to be higher and which have to become the focus of thorough detailing.
