In Figure 2b,interstorey drift and horizontal displacement from pushover and dynamic
analyses are compared,considering total drift of 1.0%.It can be observed that interstorey drift
obtained from dynamic analysis are maximum at the third floor and close to results obtained from
first-mode and DAP analyses.Comparison of static against dynamic results,in terms of both
capacity curves as well as inter-storey drift profiles,leads to the conclusion that displacementbased
adaptive pushover features the highest potential to better reproduce results of incremental

dynamic analysis.In Table 2,displacement ductility (μ),computed as the ratio between ultimate
top displacement (corresponding to attainment of ultimate concrete compression strain) and its
yield counterpart (attainment of yielding stress fy of steel bars) are reported.
Frame structures depicted in Figure 3 are considered for second and third case studies.
Mechanical properties of materials are reported in Table 1.Distributed vertical loadings on beams
is equal to 20 kN/m.In Figure 4a,for the 2nd case study,comparison between results of pushover
procedures and incremental dynamic analyses is shown.Note that,contrarily to the first casestudy,
not all values obtained by dynamic analyses are inside the area enclosed between two
capacity curves from conventional pushover analyses [6].For this case-study,all pushover curves
are grouped close together,hence no clear winner can be identified.In Figure 4b,for the 3rd case
study,comparison between results of
