defined structural systems have never been subjected to significant level of earthquake ground
shaking and the potential response characteristics and the ability to meet the design performance
objectives is untested and unknown. Based on these facts, this publication provides a methodology
to quantify the seismic performance factors for untested structural systems and for newly proposed
structural systems. The methodology provided by FEMA P695 would be used for the performance
evaluation of the newly proposed sheet-in shear wall system.
5.3 Building Archetype
Behaviors of a proposed seismic-force-resisting system are investigated through the use of
archetypes. An archetype (FEMA P695) is a prototypical representation of a seismic-force-
resisting system. Archetypes are intended to reflect the range of design parameters and system
attributes that are judged to be reasonable representations of the feasible design space and have a
measurable impact on system response. They are used to bridge the gap between collapse
performance of a single specific building and the generalized predictions of behavior needed to
quantify performance for an entire class of buildings.
It is expected that the set of index archetype configurations will generally include about
twenty to thirty specific structural configurations. The configuration design variables could be
occupancy and use, elevation and plan configurations, building height and seismic design category,
etc. Index archetype configurations are assembled into performance groups that reflect major
differences in configurations.
Two groups of archetypes were studied in this research. They were a group of office
building archetypes and a group of hotel building archetypes, shown in Table 5.1.
