PVElite 5.0, 2003 1993-2003 by COADE Engineering Software TC "Natural Frequency Calculation" /f C The Natural Frequencies for the vessel have been computed iterativelyby solving a system of matrices. These matrices describe the massand 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 14.5521 Hz.The Natural Frequency for the Vessel (Ope...) is 14.3855 Hz.PVElite 5.0, 2003 1993-2003 by COADE Engineering Software TC "Wind Load Calculation" /f C Determination of the Gust Response Factor from the CommentaryWind Analysis ResultsUser Entered Importance Factor is 1.000
ASCE-7 Gust Factor (Gh, Gbar) Dynamic 1.301
ASCE-7 Shape Factor (Cf) for the Vessel is 0.603
User Entered Basic Wind Speed 100.0 mile/hr
Exposure Category C
Table Lookup Value Alpha from Table C6 7.0000
Table Lookup Value Zg from Table C6 900.0000
Table Lookup Value Do from Table C6 0.0050
The Velocity Pressure Coefficient is determined as follows:Kz = 2.58( z/zg )^(2/Alpha) where z is the Elevation of interest
Kz = 2.58( z/900 )^(2/ 7.0)
Wind Vibration CalculationsThis evaluation is based on work by Kanti Mahajan and Ed ZorillaNomenclature
Cf - Correction factor for natural frequency
D - Average internal diameter of vessel ft.
Df - Damping Factor
Dr - Average internal diameter of top half of vessel ft.
f - Natural frequency of vibration (Hertz)
f1 - Natural frequency of bare vessel based on a unit value of (D/L)(10^4)
L - Total height of structure ft.
Lc - Total length of conical section(s) of vessel ft.
tb - Uncorroded plate thickness at bottom of vessel in.
V30 - Design Wind Speed provided by user mile/hr
Vc - Critical wind velocity mile/hr
Vw - Maximum wind speed at top of structure mile/hr
W - Total corroded weight of structure lb.
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 - Vibration Possibility, 25.00000 no possibility.
Vp = W / ( L * Dr)
Vp = 19508 / ( 28.48 * 3.062^2 ) = 73.056
Since Vp is > 25.0000 no further vibration analysis is required !

Membrane Stress per Unit Pressure - Shell: Fs = Ds / (2 * Ts) Times p
Fs = 51.125 / (2 * 0.875) Times p
Fs = 29.214 Times p psi
Membrane stress for unit pressure - Nozzle: Fn = Dn / (2 * Ts) * p
Fn = 6.345 / (2 * 0.280) * p
Fn = 11.330 * p psi
