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 9.12625 Hz.
The Natural Frequency for the Vessel (Ope...) is 8.23333 Hz.

Wind Analysis Results
Wind Load Results per IBC 2009:
Note: Per Section 1609 of IBC 2003/06/09 these results are also applicable for the determination of Wind Loads on structures (1609.1.1).
User Entered Importance Factor is 1.150 Gust Effect Factor (Ope)(G or Gf) Dynamic 0.970 User entered Beta Value ( Operating Case ) 0.0100 Shape Factor (Cf) 0.557 User Entered Basic Wind Speed 85.0 mile/hr
Sample Calculation for the First Element
The ASCE code performs all calculations in Imperial Unitsonly. The wind pressure is therefore computed in these units.
Value of [Alpha] and [Zg] Exposure Category = 3 (C) thus from Table C6-2: Alpha = 9.500 : Zg = 10800.000 in
Effective Height [z] = Centroid Hgt. + Vessel Base Elevation = 74.488 + 38.000 = 112.488 in = 9.374 ft. Imperial Units
Compute [Kz] Because z (9.374 ft.) < 15 ft. = 2.01 * ( 15 / Zg ) 2 / Alpha
= 2.01 * ( 15 / 900.000 )2 / 9.500
= 0.849
Type of Hill: No Hill
Directionality Factor for round structures [Kd]: = 0.95 per [6-6 ASCE-7 98][6-4 ASCE-7 02/05]
As there is No Hill Present: [Kzt] K1 = 0, K2 = 0, K3 = 0
Topographical Factor [Kzt] = ( 1 + K1 * K2 * K3 )² = ( 1 + 0.000 * 0.000 * 0.000 )² = 1.0000
Basic Wind Pressure, Imperial Units [qz]: = 0.00256 * Kz * Kzt * Kd * I * Vr(mph)² = 0.00256 * 0.849 * 1.000 * 0.950 * 1.150 * (85.000 )² = 17.153 psf
Force on the first element [F]: = qz * Gh * Cf * WindArea = 17.153 * 0.970 * 0.557 * 12201.168 = 785.450 lbf

Cf - Correction factor for natural frequency D - Average internal diameter of vessel in Df - Damping Factor < 0.75 Unstable, > 0.95 Stable Dr - Average internal diameter of top half of vessel in f - Natural frequency of vibration (Hertz) f1 - Natural frequency of bare vessel based on a unit value of (D/L²)(104) L - Total height of structure in Lc - Total length of conical section(s) of vessel in 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 lbf Ws - Cor. vessel weight excl. weight of parts which do not effect stiff. lbf Z - Maximum amplitude of vibration at top of vessel in Dl - Logarithmic decrement ( taken as 0.03 for Welded Structures ) Vp - Vib. Chance, <= 0.116E-01 (High); 0.116E-01 < 0.145E-01 (Probable) P30 - wind pressure 30 feet above the base
Check other Conditions and Basic Assumptions: #1 - Total Cone Length / Total Length < 0.5 0.000 / 282.772 = 0.000
#2 - ( D / L² ) * 104 < 8.0 (English Units) - ( 5.81 / 23.56² ) * 104 = 104.622 [Geometry Violation]
Compute the vibration possibility. If Vp > 0.145E-01 no chance. [Vp]: = W / ( L * Dr²) = 37967 / ( 282.77 * 66.366² ) = 0.30484E-01
Since Vp is > 0.145E-01 no further vibration analysis is required !

Check Approximate Fundamental Period from 9.5.5.3.2-1 [Ta]: = Ct * hnx where Ct = 0.020, x = 0.75 and hn = Total Vessel Height = 0.020 * ( 299.27170.75) = 0.223 seconds
The Coefficient Cu from Table 9.5.5.3.1 is : 1.400
Fundamental Period (1/Frequency) [T]: = ( 1/Natural Frequency ) = ( 1/8.233 ) = 0.121
Check the Min. Value of T which is the Smaller of Cu*Ta and T: = Minimum Value of (1.400 * 0.223 , 0.121 ) = 0.1215 per 9.5.5.3
Compute the Seismic Response Coefficient per 9.5.5.2.1-1 [Cs]: = Sds / ( R / I ) = 0.603 / ( 2.00 / 1.25 ) = 0.3768
Check the Maximum value of Cs per eqn. 9.5.5.2.1-2 : = Sd1 / ( T * ( R / I ) ) = 0.591 / ( 0.12 * ( 2.00 / 1.25 ) ) = 3.0386
Check the Minimum value of Cs per equation 9.14.5.1-1 [Cs]: = 0.14 * 0.6028 * 1.25 = 0.1055
Total Base Shear = Cs * Total Weight (Eqn. 9.5.5.2-1) [V]: = 0.3768 * 38650.3 = 14561.99 lbf
Distribute the Base shear force to each element according to the equationsFx = Cvx * V (eqn. 9.5.5.4-1 ) and the vertical distribution factorCvx = Wx*hxk/( Sum of Wi*hik ) and k is an exponent which is relatedto the period of Vibration.
In this case, the value of k was 1.0000 .

Note on the Cut Length Calculation: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.
Please Note: In the case of Oblique Nozzles, the Outside Diameter mustbe increased. The Re-Pad WIDTH around the nozzle is calculated as follows:Width of Pad = (Pad Outside Dia. (per above) - Nozzle Outside Dia.)/2
