According　to　the　structure　design　requirement　of　the　National　Fitness　Center　in　Ejin　Horo　Banner,　Inner　Mongolia,　the　size　of　the　nodal　displacement　and　the　stress　change　of　prestressed　cable　under　initial　prestressing　force　and　temperature　were　researched　using　finite　elements　method.　Rational　tensioning　temperature　and　appropriate　compensation　measures　of　initial　prestressing　force　loss　because　of　temperature　effect　were　investigated.　The　influence　of　the　temperature　effect　was　analyzed　under　initial　prestress.　The　results　show　that　temperature　action　on　the　cable　dome　structure　especially　the　outer　cable　and　strut　stress　can　not　be　ignored.　In　the　design　of　tensioned　prestress　level,　not　only　the　different　influences　of　construction　temperature　and　material　cutting　temperature　should　be　considered　respectively,　but　also　the　safety　of　structure　under　temperature　effect　should　be　guaranteed　for　normal　service　condition.　The　impact　of　temperature　effects　parameters　on　the　static　behavior　of　cable　dome　structure　is　significant.
