Several cases of four span viaducts,
supported by single-column bents were analyzed. Two different types of
constrains (pinned and free) at the abutments were considered. The results of
the N2 method were compared with the results, obtained from inelastic
time-history analysis. N2 procedure combines inelastic static (push-over)
analysis of the MDOF system and inelastic dynamic analysis of an equivalent SDOF
system. In general, the N2 method was able to provide reliable estimates of
global seismic response of regular bridges. However, in some cases, it failed to
predict the actual response. This was particularly true in the cases when the
influence of highermodes were important and in torsionally sensitive viaducts.
In torsionally sensitive, asymmetric viaducts with rollers at the abutments, the
inelastic time-history analysis resulted in nearly uniform distribution of
displacements in transverse direction, while the N2 method indicated much larger
displacements at the flexible side of the structure [COBISS.SI-ID 714337]
