It　is　generally　evaluated　that　pilotis　buildings　are　not　safe　enough.　However,　the　technique　of　the　confined　concrete　columns　with　high　ductility　will　give　an　approach　of　solution.　This　paper　introduce　the　concept　of　the　pilotis　building　which　is　designed　as　the　energy　absorbing　type　structure,　and　propose　to　use　the　confined　concrete　columns　with　high　ductility,　namely　soft　first　story　structure,　for　improving　the　seismic　performance　of　the　pilotis　buildings.　Through　the　case　studies　on　the　pilotis　buildings　of　two　kinds　of　types,　the　seismic　response　analysis　is　carried　out　for　25,　50　and　75Kine　ground　motions,　respectively,　and　it　is　discussed　for　the　seismic　performance,　such　as　the　effect　of　the　different　stiffness　ratios　and　the　diameters　of　columns,　and　so　on.
