Based　on　the　conceptual　design　of　an　advanced　wind　turbine　tower　system,　use　of　ultra-high-performance　cementitious　composites　material　with　compressive　strength　of　200　MPa　(UHPC-200)　is　proposed　to　ensure　high　durability　and　ductility　of　the　UHPC　hybrid　wind　turbine　tower.　Key　design　parameters　are　proposed　for　the　structural　design　of　a　3-MW　wind　turbine.　The　material　properties,　mixing　compositions,　simplified　constitutive　relationship,　and　model　parameters　are　outlined.　Using　nonlinear　finite　element　analysis,　the　effects　of　wall　thickness,　wall　thickness　ratio,　and　prestressing　tendon　on　the　structural　performance　including　the　longitudinal　stress　field,　lateral　displacement,　stress　concentration　at　the　transition　zone　between　the　middle　and　bottom　segments　are　evaluated.　Based　on　the　stress-field　analysis,　the　design　limitation　of　the　segmental　wall　thickness　and　its　ratio　is　recommended.　The　numerical　results　show　that　the　tower　with　the　wall　thickness　ratio　of　2:3　(i.e.,　thickness　200-300　mm)　with　prestressing　tendons　is　an　optimal　design　for　the　UHPC　hybrid　tower.　The　results　of　this　study　can　be　used　as　a　reference　for　the　engineering　design　of　a　new　type　of　UHPC　hybrid　wind　turbine　tower.
