self anchored flatbottom tanks minimum roof live load

design problems of anchoring of aboveground steel tanks

The loads which impact on them are self-weight,snow,wind,earthquake,overpressure and vacuum.When the earthquake,overpressure and wind loads have high values,it is possible that the tank overturn or going to slide.To eliminate the threat from free moving,the steel facilities are often anchored to the foundation.design problems of anchoring of aboveground steel tanks The loads which impact on them are self-weight,snow,wind,earthquake,overpressure and vacuum.When the earthquake,overpressure and wind loads have high values,it is possible that the tank overturn or going to slide.To eliminate the threat from free moving,the steel facilities are often anchored to the foundation.[DOC]AGENDA ITEM 650-472 Load Combinations self anchored flatbottom tanks minimum roof live load#0183;Web viewCone roofs on API 620 tanks tend to be self-supporting; self-supporting cones have a roof slope between 9.5o and 37o,or a roof-height-to-tank-diameter ratio (f/D) of 0.084 to 0.377.Cone bottoms have a greater profile range,varying from nearly flat to about 45o,or an f/D of 0.5.
