||KILAR, Vojko, FAJFAR, Peter. On the applicability of
pushover analysis to the seismic performance evaluation of asymmetric buildings.
European earthquake engineering, 2001, anno 25, n. 1, str. 20-31, graf.
||In the paper the applicability of pushover analysis to the
seismic design and evaluation of asymmetric building structures is explored.
Specialattention has been paid to a simplified variant of pushover analysis,
which is based on the bilinear idealization of force - displacement
relationships for structural macroelements. Three variants of a regular
reinforced concrete frame building structure, designed according to Eurocode 8,
are used as test examples. The results obtained with pushover analysis have been
compared with the results of time-history analyses. Simple pushover analysis has
been used to determine the BST surface and corresponding torque-displacement
diagrams. It is concluded that pushover analysis is a viable approach for the
seismic performance evaluation of torsionally stiff building structures. The
results also demonstrate that the analysed buildings are capable of resisting
ground motions which are much stronger than the design ground motion
