Abstract:
Recent earthquakes have shown that buildings designed
for life safety could sustain severe damage to
structural and nonstructural elements and building
contents. In the U.S., several groups have proposed
performance-based seismic design approaches to produce
buildings that will perform during earthquakes in
conformance with the objective of design, such an
immediate occupancy and collapse prevention. In the
design process, the response of structural members and
systems are checked against pre-established threshold
levels of performance which are usually established by
laboratory tests. This paper examines the influence of
testing protocol on the outcome of experimental work
which establishes threshold levels of structural
responses to seismic loads.
