Abstract：

FE　models　of　both　the　single-layer　Kiewitt-8　reticulated　domes　with　a　span　of　60m　and　the　cylindrical　impactor　were　developed　incorporating　ANSYS/LS-DYNA.　Afterward,　fourteen　groups　impact　are　simulated　by　changing　the　impact　position　or　impacted　angle　on　reticulated　dome,　and　impact　velocity　and　mass　of　impactor　are　changed　for　each　group　impact.　On　the　basis　of　large　numbers　of　numerical　simulations,　characteristics　of　dynamic　response　for　reticulated　dome　under　impact　are　shown.　And　four　failure　modes　(Members　slightly　damaged,　Local　collapse　of　dome,　Global　collapse　of　dome,　Members　shear　failed)　are　presented　for　single-layer　Kiewitt-8　reticulated　dome　under　diverse　impact.　The　distributing　of　failure　modes　for　the　fourteen　types　impact　are　different　from　each　other,　and　the　adverse　position　and　angle　are　summrized.　©　(2012)　Trans　Tech　Publications.
