Influence of Internal Inward Pressure on Stability of Open

The results of wind tunnel tests indicate that there is an internal inward pressure induced by wind excitation when open-top tanks are examined,but not when close-top tanks are examined.This internal pressure is considered in many design documents outside of the U.S.,however,ASCE-7 and API 650 do not explicitly address this factor.Influence of Internal Inward Pressure on Stability of Open The results of wind tunnel tests indicate that there is an internal inward pressure induced by wind excitation when open-top tanks are examined,but not when close-top tanks are examined.This internal pressure is considered in many design documents outside of the U.S.,however,ASCE-7 and API 650 do not explicitly address this factor.Full text of API 12F Specification for Shop Welded Tanks 3.5 SIZE Tanks under this specification shall be furnished in the sizes and dimensions as stipulated in Table 1 ,columns 1 through 7,and Fig.1,as specified on the purchase order.BOTTOM DESIGN 3.6 TYPE ' The tank bottom shall be flat,or of the type A (unskilled) or type B (skirted) cone design,as specified on the purchase order.
