the U.S. Network for Earthquake Engineering Simulation (NEES) and Japan’s
National Institute of Earth Science and Disaster Prevention, a full-scale
shaking table test of a 5-story base-isolated was carried out at Japan’s Hyogo
Earthquake Engineering Research Center (E-Defense) in 2011. The building was
tested with two different isolation systems (triple pendulum bearings and a
hybrid system of lead-rubber bearings and low-friction rolling cross-linear
bearings) and in the fixed-base configuration. The tested building had a
realistic floor system, nonstructural components (suspended ceilings, sprinkler
piping and interior walls), and furnishings, and was subjected to strong
earthquake shaking.</span></p>

concept of seismic isolation to protect the building from damage in very strong
earthquake shaking; for instance, displacement demands across the isolation
system were more than twice what has been observed in any previous earthquake
event. However, the nonstructural components and furnishings were not
completely protected from damage, and the tests showed that these items were
sensitive to the vertical component of ground shaking, which is unaffected by
the seismic isolation system. While the overall performance of the isolation
systems was very impressive when considered against other available options for
seismic protection, the tests highlight the challenge of designing a building
to remain immediately operational following a large earthquake. This
presentation will summarize the test program, present the major findings, and
discuss future directions in research and design practice.</span><span style="font-family:"Times New Roman",serif"></span></p><p class="MsoNormal" style="margin:0in 0in 0.0001pt;font-size:12pt;font-family:Calibri,sans-serif"><span style="font-size:10.5pt;font-family:"Helvetica Neue";color:rgb(51,51,51);background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial"><br></span></p><p class="MsoNormal" style="margin:0in 0in 0.0001pt;font-size:12pt;font-family:Calibri,sans-serif"><span style="font-size:10.5pt;font-family:"Helvetica Neue";color:rgb(51,51,51);background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial"></span></p><div style="text-align:center"><img src="cid:ii_jndxzdif0" alt="Lehigh.png" width="314" height="78" style="margin-right:0px"><br></div><div><br></div><div><div style="text-align:center"><img src="cid:ii_jndy07541" alt="nsf-small.jpg" width="45" height="45"><br></div></div></div>
