Comparativeanalysis on cable tensioning scheme of multiple square loops-string dome

Translated Abstract

Multiple　square　loops-string　dome　(　MSLSD)　has　quite　various　mechanics　under　different　ca-ble　tensioning　sequences.　In　order　to　optimize　the　cable　tensioning　sequences,　the　first　MSLSD　project　that　is　Fuzhou　Olympics　Gymnasium　was　taken　as　research　background.　And　the　investigations　are　car-ried　on　to　proposed　two　different　cables　tensioning　schemes.　Based　on　the　3D　finite-element　model,　the　internal　forces　and　deformations　of　the　MSLSD　under　different　cables　tensioning　schemes　are　discussed.　The　process　of　cable　tensions　is　simulated　by　cooling　method.　The　analysis　results　shows　that　the　roof　in-ternal　forces　and　deformation　during　cable　tensioning　stage　for　two　schemes　are　quite　different,　although　the　final　results　are　nearly　the　same.　During　the　tensioning　process,　roof　deformation　and　internal　force　of　grillage　girder　are　obviously　less　for　the　1st　tensioning　schemes.　Therefore,　considering　the　safety　dur-ing　construction,　the　1st　tensioning　schemes　are　recommended,　whose　sequence　is　＂external　cables　square　loop-middle　cables　square　loop-internal　cables　square　loop-cables　of　string　beam＂.
