To　meet　the　requirements　of　universal　hinged　supports　with　extra　large　tension　and　shear　bearing　capacity,　this　paper　presents　the　design　and　analysis　of　an　innovative　heavy-duty　cast　steel　universal　hinged　support　with　extra　large　tension　and　shear　capacity　based　on　a　prototype　support.　A　3D　FE　model　was　constructed　with　the　nonlinearities　of　contacts,　materials　and　geometry　and　verified　with　test　results.　During　FE　modeling,　a　3D　entity　modeling　software　SOLIDWORKS　was　utilized　to　set　up　the　solid　model,　which　was　then　imported　in　HYPERMESH　to　construct　the　FE　model　and　finally　solved　using　ANSYS.　Mechanical　performance　of　the　support　in　three　typical　load　combination　cases　was　investigated　using　the　model　and　checked　according　to　a　Chinese　national　code　CECS　235:2008＇Technical　specification　for　application　of　connections　of　structural　steel　casting＇.　Analysis　showed　that　stress　of　the　support　under　design　load　exceeded　stress　limits.　After　several　tentative　analyses,　the　support　details　were　revised　including　additional　stiffeners　and　loading　path　changes.　The　modified　support　has　reasonable　construction　details,　direct　force　path,　reliable　performance,　and　can　not　only　satisfy　the　requirements　the　project　(tension　4103kN,　compression　5970kN　or　shear　3254kN,　and　meantime　has　the　ability　of　universal　rotation),　but　also　has　large　safety　margin.　Based　on　the　research,　suggestions　are　proposed　for　the　design　of　this　kind　of　heavy-duty　cast　steel　universal　hinged　supports.
