Experimental Facility of UC Davis, the tests were designed to capture the time-dependent nature of liquefaction-induced downdrag on axially loaded piles in interbedded soil deposits. A variety of conditions were considered regarding the pile properties, the
soil profile, and motions, yielding an unparalleled set of case histories. The dataset includes extensive documentation: data reports together with design schematics and videos which detail the experiments, open-source codes for processing, recorded and processed
data, and help documents and metadata on how to navigate the dataset. Details are also provided on the sensing methods developed specifically for these tests: internal pile strain gages to measure axial loads, low-cost transducers for measuring dynamic pore
pressures, a contactless method using a line laser with a camera to measure surface settlement, use of high-speed cameras and 3D stereophotogrammetry to measure 3D movements, and use of laser scanner to measure surface settlements. The dataset offers versatility
for its users for a broad range of applications: from advanced instrumentation, to site response and reconsolidation analyses, to soil-structure-interaction analyses.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:7.5pt;background:white"><span style="font-size:12.0pt;font-family:"Helvetica Neue";color:#333333">This webinar will discuss the centrifuge model testing design with a focus on the targeted mechanisms, the instrumentation
