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

Wind Load Results per ASCE-7 93:

Sample Calculation for the First Element:

Rougness Factor = 1.000

Values [cf1] and [cf2] Because RoughFact = 1 and DQZ > 2.5 and H/D < 7.0

Interpolating to find the final cf:

Because H / D < 7.0

CF = CF1 + (CF2-CF1)*( H/D - 1) / (7 - 1)

= 0.500 + (0.600 -0.500 )*( 2.671 - 1) / (7 - 1)

= 0.528

Value of Alpha, Zg is taken from Table C6-2 [Alpha, Zg] For Exposure Category C:

Alpha = 7.000 , Zg = 900.000 ft.

height of Interest for First Element [z] = Centroid Hgt + Base Height

= 0.588 + 0.000 = 0.588 ft.

but: z = Max(15.000 , 0.588 ) = 15.000 ft.

Note: Because z < 15 feet, use 15 feet to compute kz.

Velocity Pressure Coefficient [kZ]: = 2.58( z/zg )^(2/Alpha) : z is Elevation of First Element

= 2.58( 15.000 /900 )^(2/7.0 )

= 0.801

Determine if Static or Dynamic Gust Factor Applies Average Dia. = Total Wind Area / Vessel Height

= 31.511 / 9.173 = 2.671 ft.

Vibration Frequency = 26.786 Hz

Because H/D < 5 And Frequency > 1.0: Static Analysis Implemented

The following two calculations allow for any user units

Compute [tz] = 2.35 * Sqrt(DO / VesselHtg/30(feet)^(1/Alpha)

= 2.35 * Sqrt(0.005 / 9.173 )^(1/30.000 )

= 0.197

Compute [Gh] = 0.65 + 3.65 * tz

= 0.65 + 3.65 * 0.197 = 1.368

Wind Pressure - (performed in Imperial Units) [qz] Importance Factor: I = 1.000

Wind Speed = 70.000 mile/hr

qz = 0.00256 * kZ * (I * Vr)²




= 0.00256 * 0.801 *(1.000 * 70.000 )² = 10.046 psf

Force on the First Element [Fz] = qz * Gh * CF * Wind Area

= 10.046 * 1.368 * 0.528 * 509.971

This evaluation is based on work by Kanti Mahajan and Ed Zorilla

Nomenclature

Cf - Correction factor for natural frequency

D - Average internal diameter of vessel ft.

Df - Damping Factor < 0.75 Unstable, > 0.95 Stable

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/L²)(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 - Vib. Chance, <= 0.200E+02 (High); 0.200E+02 < 0.250E+02 (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 / 8.282 = 0.000

#2 - ( D / L² ) * 10^(4) < 8.0 (English Units)

- ( 3.51 / 8.28² ) * 10^(4) = 511.514 [Geometry Violation]

Compute the vibration possibility. If Vp > 0.250E+02 no chance. [Vp]: = W / ( L * Dr²)

= 1412 / ( 8.28 * 3.470² )

= 14.168

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

= 1412 * 0.03 / ( 8.28 * 3.470² )

= 0.425

Compute the critical wind velocity [Vc]: = 3.4 * f * Dr

= 3.4 * 26.786 * 3.470

= 316.016 mile/hr

Compute the velocity at the top of the tower [Vw]:




= V30 * ( L / ( 30 + BaseHeight ))^(0.143)

= 70.00 * ( 8.28 / ( 30 + 0.0 ))^0.143

= 58.232 mile/hr

Compute the maximum gust velocity using the gust response factor Gh [Vg]: = Vw * Gh

= 58.232 * 1.368

= 79.684 mile/hr

Since Vc is greater than Vg the dynamic deflection Z, does notneed to be computed.

The Natural Frequency for the Vessel (Ope...) is 26.7856 Hz.

Actual Nozzle Inside Diameter Used in Calculation 18.814 in.

Actual Nozzle Thickness Used in Calculation 0.593 in.

Nozzle input data check completed without errors.

Required thickness per AD-201 of Nozzle Wall: [Int. Press] = (P*(D/2+CA))/(S-0.5*P) per AD-201

= (150.00*(18.8140/2+0.1250))/(20000-0.5*150.00)

Required thickness of Nozzle under External Pres. 0.0327 in.

Compute Thickness limits for Hub type Nozzles: Tl1 = 0.5 * sqrt( rm * tn ) + K

Tl1 = 0.5 * sqrt( 10.4695 * 1.8750 ) + 0.3750 = 2.5903 in.

Tl3 = 2.5 * t

Tl3 = 2.5 * 0.2293 = 0.5732 in.

Tl4 = 1.73 * x + 2.5 * tp + K

Tl4 = 1.73 * 1.4070 + 2.5 * 0.4680 + 0.3750 = 3.9791 in.

Tl5 = L + 2.5 * tp

Tl5 = 5.0000 + 2.5 * 0.4680 = 6.1700 in.

Tlnp = Min( Max( TL1, TL4 ), TL3, TL5 ) ( h < 2.5*tn + K )
