The　static　stability　capacity　is　the　main　index　to　measure　the　whole　mechanical　performance　of　single-layer　latticed　shells.　Three　single-layer　cylindrical　latticed　shells　with　different　height　to　span　ratio　were　modeled,　and　their　seismic　damage　were　assessed　by　the　degradation　of　static　stability　capacity　incurred　by　earthquakes.　Two　different　static　load　patterns　were　considered:　dead　load　and　the　combination　of　dead　load　and　half　span　live　load.　The　results　show　that　the　damage　assessment　method　is　applicable　to　single-layer　cylindrical　latticed　shells,　and　the　static　load　patterns　have　no　big　influence　on　the　damage　assessment　of　the　single-layer　cylindrical　latticed　shells.
