摘要：

Time-history　method　is　used　to　study　the　joint　stiffness　effect　on　dynamic　stability　of　single-layer　cylindrical　reticulated　shell　fine　model　as　the　Ground　Peak　Acceleration　(PGA)　is　changing.　Meanwhile,　the　structural　parameters　such　as　rise-span　ratio　and　length-width　ratio　and　so　on　are　considered.　The　joint　stiffness　is　altered　according　to　the　change　of　the　wall　thickness　of　joint.　In　total,　4　groups　of　fine　models　are　used　in　the　example.　The　result　from　these　4　groups　of　models　is　similar.　It　shows　the　joint　stiffness　effect　on　the　dynamic　stability　of　these　structures　is　larger　when　PGA　is　smaller　(PGA　is　larger　than　collapse　acceleration),　and　this　rule　is　not　changed　when　the　structural　parameter　is　different.
