摘要：

The　collapse　mechanism　of　single-layer　cylindrical　latticed　shell　under　severe　earthquakes　is　analyzed　with　full-range　responses　method　based　on　load　domain.　Results　show　that　this　kind　of　shell　takes　on　a　very　distinct　one-way　mechanical　characteristic　along　the　span　direction,　and　its　length　to　span　ratio　has　little　influence　on　its　mechanical　performance.　There　is　a　strong　regularity　in　its　collapse　behaviour,　and　all　the　collapse　patterns　belong　to　the　dynamic　strength　failure　mode.　Its　rise　to　span　ratio　has　a　tremendous　influence　on　the　collapse　PGA,but　the　influence　has　no　fixed　regularity.　The　collapse　PGA　will　decrease　when　the　roof　mass　increases　or　there　is　initial　geometrical　imperfection,　but　the　decreased　magnitude　depends　on　the　shells.
