| Abstract: | To verify the seismic design response factors of high-rise buildings, five reference structures, varying in height from 20-
to 60-stories, were selected and designed according to modern design codes to represent a wide range of concrete wall structures.
Verified fiber-based analytical models for inelastic simulation were developed, considering the geometric nonlinearity and
material inelasticity of the structural members. The ground motion uncertainty was accounted for by employing 20 earthquake
records representing two seismic scenarios, consistent with the latest understanding of the tectonic setting and seismicity
of the selected reference region (UAE). A large number of Inelastic Pushover Analyses (IPAs) and Incremental Dynamic Collapse
Analyses (IDCAs) were deployed for the reference structures to estimate the seismic design response factors. It is concluded
that the factors adopted by the design code are adequately conservative. The results of this systematic assessment of seismic
design response factors apply to a wide variety of contemporary concrete wall buildings with various characteristics. |
