Comparative Evaluation of Seismic Assessment Methodology

ABSTRACT: Results of seismic damage evaluation of a tall reinforced
concrete building are presented. Plastic hinge formation patterns obtained
by using DRAIN-2D and IDARC computer programs for dynamic analysis
are compared. Damage indices given by IDARC are interpreted and their
implications compared with those of drift ratios. Results of static
push-over analysis are compared with those of inelastic dynamic time
history analysis. Moreover, the result of collapse mechanism approach is
compared with that of static push-over analysis. It is shown that simple
collapse mechanism approach can predict the failure mode given by static
push-over analysis for this building. It is concluded that drift limits in
codes do not necessarily predict the degree of damage that this type of
construction can sustain in severe earthquakes.
