To　put　stretch　forming　latticed　structure　(SFL)　into　practice,　the　paper　puts　forward　two　methods　which　include　tensioning　group　by　group　and　simultaneously　tensioning　step　by　step.　Based　on　the　effect　on　structural　axial　force　of　upper　chord　by　tensioning　method,　a　detailed　analysis　of　axial　force　distribution　and　comparison　is　carried　out　by　theoretical　method　basing　on　ANSYS　finite　element　program.　The　study　shows　that　method　tensioning　group　by　group　is　feasible　program.　It　is　necessary　to　study　the　whole　forming　process　of　SFL,　and　it　is　important　to　reasonably　select　structural　configuration　of　middle　party　of　SFL.
