In　order　to　overcome　the　disadvantages　of　the　current　bearings,　a　new　kind　of　three-dimensional　seismic　isolation　bearings　is　then　introduced　in　this　paper.　The　new　bearing　is　combined　a　friction　sliding　system　in　horizontal　direction　with　a　helical　springs　or　disc　springs　in　the　vertical　direction.　Based　on　the　conception　model,　two　practical　bearings　are　designed　and　manufactured.　Experimental　study　on　the　characteristics　of　the　bearings　is　carried　out　on　shaking　table.　Meanwhile,　a　theoretical　model　of　the　bearing　is　established.　Finally,　some　details　related　to　the　dynamic　analysis　of　isolated　spatial　structures　are　discussed.　It　is　shown　that　the　proposed　bearings　perform　satisfactorily　seismic　isolation　properties,　and　the　periods　of　the　isolated　structure　is　prolonged,　meanwhile,　the　axial　force　response　is　reduced　50　percent　as　well.
