Imperfection-sensitivity of unanchored aboveground open

The tanks were assumed to be self-anchored and are supported by an elastic soil foundation which is modeled as a series of elastic springs.The API 650 does not require mechanical anchorage for seismic purposes,provided that the anchorage ratio J is not more than 1.54.The anchorage ratio J depends on the seismic acceleration parameters.Therefore,the assumption of self-anchored tank holds true up toImperfection-sensitivity of unanchored aboveground open A numerical analysis is conducted on several unanchored aboveground,open-top,steel,welded,liquid-containing storage tanks with imperfections subjected to seismic forces.Nonlinear material properties,nonlinear geometry deformations,and a flexible soil foundation idealized by a series of elastic springs are employed in order to simulate as-built field conditions of the tank at the time of INTRODUCTION IN DESIGN OF ABOVEGROUNDThe current thesis examines aboveground vertical steel cylindrical tanks made by carbon or low alloy steels with volume from 100 m 3 up to 100 000 m 3 for water,condensate,spirits,milk,oil and oil products.The tanks have welded shell and bottom and are not used when there is an additional internal
