In　order　to　study　the　construction　method　and　mechanical　properties　of　rigid　bracing　dome,　Geiger　rigid　bracing　dome　with　6　m　of　diameter　was　designed.　Construction　method　is　the　lever　assembly　in　the　center　of　site　and　tension　gradually　upgrade.　Test　model　was　studied　for　two　cases　of　temporary　support　and　no　temporary　support.　Construction　forming　analysis　of　model　test　was　carried　out.　Construction　tensioning　method　was　studied　for　eight　directions　or　four　directions　or　two　directions　symmetric　stretching.　Mechanical　properties　of　structure　were　studied　at　full-span　load　or　half-span　load.　The　experimental　results　were　compared　with　the　finite　element　analysis　results.　The　results　show　that　construction　method　takes　full　account　of　structure　features　of　rigid　bracing　dome,　is　simple　and　efficient,　and　can　be　applied　to　practical　engineering.　The　FEDR　results　of　member　internal　force　and　joint　coordinates　are　in　good　agreement　with　the　experimental　values.　Structure　of　temporary　support　and　no　temporary　support　can　use　this　construction　method.　Because　the　deviations　of　experimental　values　and　FEDR　method　values　of　different　tensile　test　schemes　are　within　7.8%,　according　to　the　needs　of　practical　engineering,　appropriate　symmetric　stretching　can　be　selected.　The　finite　element　analysis　results　are　in　good　agreement　with　the　static　test　results.　©,　2015,　Science　Press.　All　right　reserved.
