Out-of-Plane Edge Deflection Analysis - APl-653 Appendix B

Tank No.: 3

Fonnula for Out-of-Plane Deflection: IS) < or= (L z x Y x 11) / [2(E x H)]

Where:

S = deflection, in feet

L = arc length, in feet 0.016 feet= 0.19 inches

Y = yield strength, in psi L: 11.2 feet

E = Young's modulus, in psi Y: 30,000 psi

H = tank height, in feet E: 29.5 X 10"6 psi

H: 31.75 feet

Sallow: 0.022 feet

Out-of-Plane edge settlement is acceptable per APl-653.
