General Tank Data Roof Specification

8/17/2019 CAU2016 Tank.pdf


Intergra&h TA'( is a com&rehensive: eas)#to#use soft/are &ackage for the design:anal)sis and evaluation of oil storage tanks! It &rovides users /ith quick and accuratedesigns for ne/ tanks and evaluation of e+isting tanks!

TA'( &erforms calculations in accordance /ith the latest A2I -tandards 309 and30,! Anal)sis can also take into account /ind: seismic and settlement conditions &lus

calculate air venting requirements to A2I *999 -ection .!,!!

(aterial Data)ase

• The program includes following material

databases: – TA'( has man) data;ases integral to the &ackage /hich make it eas) to select

standard data for accurate anal)sis! A num;er of <- and international structuralsteel data;ases are &rovided!

– A&art from: the user can edit or customi1e the material &ro&erties as &er &ro=ectrequirement!

General Tank Data-

• This /ill ;e the starting &oint of ever) tank that )ou anal)1e!

%o&&le "tiffness - Appendi P

"hell "ettlement - AP' ()* Appendi +

• Allo/s )ou to define the measured settlement of u& to .9 &oints around the tankshell circumference!

• With the hel& of this /e can determine the o&timum cosine curve /hich most

closel) re&resents the users measured values of shell settlement! After thecosine curve is kno/n: the out#of#&lane settlement and out#of#&lane deflectioncan ;e determined!

"eismic Anal,sis - Appendi E

• Tanks ma) have to /ithstand seismic distur;ances in the normal course of theirservice life! California and a&an are seismicall) active areas: and the accelerations to/hich the tank ma) ;e su;=ected must ;e ;uilt into the tank at the design stage;efore construction! A&&endi+ E of A2I 309 address this as&ect of design! Here /ill see/hat ha&&ens /hen the vessel has slur&ing liquid inside after a seismic distur;ance

and ho/ /e can get shear resistance force: com;ined hoo& stress and required free;oard value!
