Experimental　data　taken　from　free-field　soil　in　1-g　shaking　table　tests　are　valuable　for　seismic　studies　on　soil-structure　interaction.　But　the　available　data　from　medium-　to　large-scale　shaking　table　tests　were　not　abundant　enough　to　cover　a　large　variety　of　types　and　conditions　of　the　soil.　In　the　study,　1-g　shaking　table　tests　of　a　3-m-height　sand　column　were　conducted　to　provide　seismic　experimental　data　about　sand.　The　sand　was　directly　collected　in-situ,　with　the　largest　grain　diameter　being　2　cm　and　containing　a　water　content　of　6.3%.　Properties　of　the　sand　were　estimated　under　the　influence　of　white　noise　plus　pulse　and　earthquake　motions,　including　the　settlement,　the　dynamic　properties　of　the　sand　column,　and　the　three　soil　layers＇　shear　modulus　degradation　relationships.　The　estimated　properties　were　then　indirectly　verified　by　means　of　finite　element　analysis.　Results　show　that　the　estimated　parameters　were　effective　and　could　be　used　in　numerical　modeling　to　reproduce　approximate　seismic　responses　of　the　sand　column.
