In　order　to　implement　the　Internal　stretch　forming　space　lattice　structure　(ISFSL)　into　practice,　structure　composing　of　ISFSL　is　fully　presented.　Taking　practically　tensioning　methods　into　consideration,　a　study　of　parameter　effect　on　the　load　process　is　carried　out　as　far　as　an　ISFSL　with　a　span　of　100　metres　long　is　concerned　by　the　theoretical　simulating　and　graph　analysis,　which　is　based　on　the　result　of　the　ISFSL　forming　study　with　a　span　of　100　metres　long.　The　parameters　include　width　and　height　of　the　upper　chord　beam　cross　section,　shape　and　area　of　the　upper　chord　ring　beam.　The　structural　properties　of　the　load　process　affected　by　the　parameters　are　also　provided,　which　show　that　width　and　height　of　the　upper　chord　beam　cross　section　is　the　most　important　factor　which　affects　the　load　process.
