In　order　to　make　sure　load　conditions　and　structures　conditions　which　lead　to　the　serious　impact　damage　to　structure,　that　is　relationship　between　maximum　response/failure　mode　and　initial　condition,　to　determine　impact　failure　rule　of　reticulated　shell.　Firstly,　better　relationship　between　impact　failure　mode　and　total　impact　energy　of　reticulated　shell　obtained　(ETK)　is　discovered.　Relationship　between　ETK　for　once　impact　failure　and　initial　impact　kinetic　energy　(E)　is　built　by　transfer　coefficient　of　kinetic　energy　(φ).　Then　coefficient　of　global　collapse　is　proposed　to　evaluate　the　anti-impact　ability　of　structure.　Moreover,　failure　law　of　global　collapse　under　different　initial　conditions　(impact　position,　impact　angle,　ratio　rise　to　span　)　is　obtained　by　numerical　analysis.
