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.

The Natural Frequency for the Vessel (Filled) is 7.47226 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

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 !
