In　this　paper,　a　model　of　topology　optimization　with　linear　buckling　constraints　is　established　based　on　an　independent　and　continuous　mapping　method　to　minimize　the　plate/shell　structure　weight.　A　composite　exponential　function　(CEF)　is　selected　as　filtering　functions　for　element　weight,　the　element　stiffness　matrix　and　the　element　geometric　stiffness　matrix,　which　recognize　the　design　variables,　and　to　implement　the　changing　process　of　design　variables　from　＂discrete＂　to　＂continuous＂　and　back　to　＂discrete＂.　The　buckling　constraints　are　approximated　as　explicit　formulations　based　on　the　Taylor　expansion　and　the　filtering　function.　The　optimization　model　is　transformed　to　dual　programming　and　solved　by　the　dual　sequence　quadratic　programming　algorithm.　Finally,　three　numerical　examples　with　power　function　and　CEF　as　filter　function　are　analyzed　and　discussed　to　demonstrate　the　feasibility　and　efficiency　of　the　proposed　method.
