The　short　specially　shaped　columns　with　concealed　columns　and　with　crossed　reinforcing　bars　are　put　forward　in　this　paper.　Through　the　tests　of　seismic　behavior　of　3　Z-shaped　column　specimens,　the　bearing　capacity,　ductility,　hysteresis　curves　and　failure　modes　in　two　engineering　horizontal　directions　of　Z-shaped　column　are　analyzed.　It　is　proved　that　the　concealed　columns　in　the　short　Z-shaped　column　can　greatly　improve　its　seismic　behavior.　Then,　based　on　the　tests　of　seismic　behavior　of　3　T-shaped,　3　+　-shaped　and　3　L-shaped　column　specimens,　the　seismic　behavior　of　the　general　specially　shaped　columns,　specially　shaped　columns　with　concealed　columns　and　specially　shaped　column　with　crossed　reinforcing　bars　are　compared　respectively　for　each　shape.　It　is　proved　that　the　crossed　reinforcing　bars　in　the　short　specially　shaped　columns　can　significantly　improve　its　seismic　behavior.　Finally,　by　applying　the　proposed　model,　a　non-linear　finite　element　analyses　is　carried　out　for　the　short　specially　shaped　columns　subjected　to　cyclic　loading.　The　analytical　results　are　in　good　agreement　with　the　test　results.
