design problems of anchoring of aboveground steel tanks

To eliminate the threat from free moving,the steel facilities are often anchored to the foundation.This solution is not recommendable,and in standards [1] and [2] it is positioned on the last place.Despite the standards recommendations when the conditions of exploitation are strait and/or extreme,the steel vertical tanks must be anchored.design problems of anchoring of aboveground steel tanks To eliminate the threat from free moving,the steel facilities are often anchored to the foundation.This solution is not recommendable,and in standards [1] and [2] it is positioned on the last place.Despite the standards recommendations when the conditions of exploitation are strait and/or extreme,the steel vertical tanks must be anchored.[DOC]Scope - American Petroleum Institute mechanically anchored tanks designing the tank and foundation#0183;Web viewInner Tank Selfanchored 2.25 1.5 Mechanically-anchored 2.5 1.5 Outer Tank (Empty) Selfanchored 2.0 n/a Mechanically-anchored 2.0 n/a The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently.
