To　solve　the　shortage　of　traditional　construction　simulation　methods　for　suspended　dome　structures,　based　on　friction　elements,　node　coupling　technology,　and　local　cooling,　the　cable　tension　preslack　method　is　proposed　in　this　paper,　which　is　suitable　for　the　whole　process　construction　simulation　of　a　suspended　dome.　This　method　was　used　to　simulate　the　construction　process　of　a　large-span　suspended　dome　case　study.　The　effects　on　the　simulation　results　of　location　deviation　of　joints,　construction　temperature,　construction　temporary　supports,　and　friction　of　the　cable-support　joints　were　analyzed.　The　cable　tension　preslack　method　was　demonstrated　by　comparing　the　data　from　the　construction　simulation　with　measured　results,　providing　the　control　cable　tension　and　the　control　standards　for　construction　acceptance.　The　analysis　demonstrated　that　the　position　deviation　of　the　joint　has　little　effect　on　the　control　value;　the　construction　temperature　and　the　friction　of　the　cable-support　joint　significantly　affect　the　control　cable　tension.　The　construction　temperature,　the　temporary　construction　supports,　and　the　friction　of　the　cable-support　joints　all　affect　the　internal　force　and　deflection　in　the　tensioned　state　but　do　not　significantly　affect　the　structural　bearing　characteristics　at　the　load　state.　The　forces　should　be　primarily　controlled　in　tensioned　construction,　while　the　deflections　are　controlled　secondarily.
