The Natural Frequencies for the vessel have been computed iteratively by solving a system of matrices. These matrices describe the mass and the stiffness of the vessel. This is the generalized eigenvalue/ eigenvector problem and is referenced in some mathematical texts.

The Natural Frequency for the Vessel (Empty.) is 84.4571 Hz.

The Natural Frequency for the Vessel (Ope...) is 84.4571 Hz.

The Natural Frequency for the Vessel (Filled) is 62.7303 Hz.

tb - Uncorroded plate thickness at bottom of vessel in.

Ws - Cor. vessel weight excl. weight of parts which do not effect stiff. lb. Z - Maximum amplitude of vibration at top of vessel in. Dl - Logarithmic decrement ( taken as 0.03 for Welded Structures ) Vp - Vib. Chance, 0.250E+02 no chance. [Vp]: = W / ( L * Dr²) = 1809/( 10.18 * 2.974² ) = 0.20107E+02

Compute the damping factor Df which is a measure of instability [Df]: = W * Dl/ ( L * Dr² ) = 1809 * 0.03/( 10.18 * 2.974² ) = 0.603

Compute the critical wind velocity [Vc]: = 3.4 * f * Dr = 3.4 * 84.457 * 2.974 = 853.878 mile/hr

Compute the velocity at the top of the tower [Vw]: = V30 * ( L / ( 30 + BaseHeight ))0.143 = 70.00 * ( 10.18/( 30 + 0.0 ))^0.143 = 59.973 mile/hr

Compute the maximum gust velocity using the gust response factor Gh [Vg]: = Vw * Gh = 59.973 * 1.351 = 80.996 mile/hr

Since Vc is greater than Vg the dynamic deflection Z, does not need to be computed.

The Natural Frequency for the Vessel (Ope...) is 84.4571 Hz.

General Notes for the above table:

The Cut Length is the Outside Projection + Inside Projection + Drop + In Plane Shell Thickness. This value does not include weld gaps, nor does it account for shrinkage.

In the case of Oblique Nozzles, the Outside Diameter must be increased. The Re-Pad WIDTH around the nozzle is calculated as follows: Width of Pad = (Pad Outside Dia. (per above) - Nozzle Outside Dia.)/2

For hub nozzles, the thickness and diameter shown are those of the smaller and thinner section.
