Abstract：Inorder toexplore themechanicalbehaviorofultra-highperformanceconcrete（UHPC）tower，itsloading condition wassimplifiedas acompression-bending member withfixedbottomandfreeupper end.The finiteelementanalysis model was establishedbyusing Midas FEANX tostudytheinfluenceofreinforcementamount，wallthicknessand towerheight onthe mechanicalbehaviorof UHPC tower.Theresultsshowedthat withthe increaseofreinforcement，thebearing capacityof UHPC tower was obviously improved；with theincrease of towerwallthickness，the bearingcapacityof UHPC tower was improved，butitscontributionwaslimited；withtheincreaseof towerheight，thebearingcapacityof UHPC towerdecreased and the damage pattern changed.
