The　experimental　study　and　numerical　simulation　by　ANSYS　are　conducted　to　the　1:10　reduced　scale　suspend-dome　model　of　the　badminton　gymnasium　for　2008　Olympic　Games.　The　mechanical　performances　of　the　model　are　studied　under　self-weight　load　at　the　state　of　single-layer　dome　before　cable　is　tensioned,　at　the　stage　of　construction,　under　design　load　and　even　3　times＇　load,　and　that　during　loaded　until　it　breaks　down.　By　comparing　the　value　drawn　from　ANSYS　and　experiment,　the　theoretic　and　experimental　data　of　the　members＇　axial　force,　the　joints＇　displacement,　the　horizontal　displacements　of　the　top　points　of　the　columns　and　the　ultimate　load　are　available.　The　influence　of　unsymmetrieal　layout　of　the　live　load　on　the　integral　stability　is　studied,　thus　gets　the　form　of　ultimate　destroy.　The　study　indicates　that　the　theoretical　value　and　the　experimental　value　matches　well　under　the　lower　load,　but　the　difference　of　them　become　large　under　larger　load　and　the　experimental　integral　stability　is　lower　than　the　theoretical　value.　The　analysis　shows　that　the　initial　defect　affects　the　performance　largely　under　large　load　and　the　numerical　simulation　can　hardly　involve　all　the　initial　defects.　The　stability　of　the　suspend-dome　is　sensitive　to　the　layout　of　the　live　load,　and　the　stability　factor　computed　by　ANSYS　is　larger　than　that　of　the　experiment　by　40%,　which　should　be　considered　in　design　and　construction.　The　ultimate　breakdown　form　is　due　to　the　expansion　of　losing　stability　from　the　local　buckling　to　the　whole　structure.
