Abstract

Several researchers found that the behavior of natural preshaken soils can be very different from artificial recent fills. This paper presents an extensive database of two very long centrifuge experiments (CS-5-1-1 and CC-5-1-1) performed both on silty and clean sand at the geotechnical centrifuge testing facility at Rensselaer Polytechnic Institute (RPI). The two experiments test the effect of seismic preshaking history on the liquefaction resistance of sandy soils. The database described herein was generated using the NEEShub online DataStore tool under the name "PRESHAKE: Centrifuge modeling of the effect of seismic preshaking on the liquefaction resistance of sands" (DOI: http://dx.doi.org/10.4231/D38K74X78). The paper discusses the tools and materials used in the experiments along with an explanation of each item in the database. Sample analyses are also presented in the paper to give an insight on the capabilities of the database for numerical and analytical applications. The paper is concluded with some possible applications along with tips and limitations of the database.
