In　this　research,　the　flush　end-plate　beam-to-column　connections　are　being　investigated　in　fire　conditions.　In　order　to　analyze　and　understand　the　behaviour　of　such　a　connection　at　ambient　and　elevated　temperatures,　a　reliable　3D　finite　element　model　of　end-plate　has　been　created　using　the　ANSYS　software.　The　model　is　capable　of　simulating　the　behaviour　of　typical　connection　configurations　in　both　steel　and　composite　framed　structures　under　fire　conditions.　This　is　a　complex　model　accounting　for　contact　interaction　between　each　component　of　this　type　of　connection.　The　surface　to　surface　contact　elements　have　been　used　for　the　entire　contact　surface　to　transfer　the　load　from　the　beam　to　the　column.　The　contact　area　include　bolts　shank　and　hole　interface,　bolt　head　and　end-plate　surface,　nuts　and　column　flange　surface.　Validation　of　the　proposed　connection　model　is　carried　out　by　comparison　against　a　range　of　available　experimental　results,　implementation　is　undertaken　within　an　advanced　finite　element　program　that　account　for　material　and　geometric　nonlinearities.　Finally,　compare　the　results　from　ANSYS　with　available　experimental　data,　it　shows　that　the　model　has　a　high　level　of　accuracy.
