Wind Analysis Results

Wind Load Results per ASCE-7 95:

Note: Per Section 1609 of IBC 2003/06 these results are also applicablefor the determination of Wind Loads on structures (1609.1.1).

User Entered Importance Factor is 1.000 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 90.0 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 = 900.000 ft.

Effective Height [z] = Centroid Hgt. + Vessel Base Elevation = 2.240 + 0.000 = 2.240 ft.

Compute [Kz] Because z (2.240 ft.) < 15 ft. = 2.01 * ( 15 / Zg ) ^(2 / Alpha) = 2.01 * ( 15 / 900.000 )^(2 / 9.500 ) = 0.849

Type of Hill: No Hill

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 * 1.000 * 1.000 * (90.000 )² = 17.602 psf

Force on the first element [F]: = qz * Gh * Cf * WindArea = 17.602 * 0.970 * 0.557 * 5076.000 = 335.536 lb.

Wind Vibration Calculations

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 / 19.333 = 0.000

#2 - ( D / L² ) * 10^(4) < 8.0 (English Units) - ( 4.76 / 19.33² ) * 10^(4) = 127.388 [Geometry Violation]

Compute the vibration possibility. If Vp > 0.250E+02 no chance. [Vp]: = W / ( L * Dr²) = 12560 / ( 19.33 * 3.723² ) = 0.46871E+02

Since Vp is > 0.250E+02 no further vibration analysis is required !

Earthquake Analysis Results per ASCE95

Check the Period (1/Frequency) from 9.2.3.3Ta = Ct * hn^(3/4) where Ct = 0.20 and hn = total Vessel HeightTa = 0.020 * ( 20.2500^(3/4)) = 0.191 seconds

The Coefficient Cu from Table 9.2.3.3 is 1.200

Check the Min. Value of T which is the Minimum of Cu*Ta and TT = Minimum Value of ( Cu * Ta, 1/Fn ) = 1.2000

Compute the Seismic Response Coefficient Cs per 9.2.3.2.1Cs = 1.2 * Cv / ( R * T^(2/3) )Cs = 1.2 * 0.5600 / ( 2.00 * 0.0312^(2/3) ) = 3.3921

Check the minimum value of Cs per eqn. 9.2.3.2-2Cs = Minimum Value of ( Cs, 2.5 * Ca / R )Cs = Minimum Value of ( 0.5000 , 2.5 * 0.4000 / 2.0000 ) = 0.5000

Compute the Total Base Shear V = I * Cs * Total WeightV = 1.000 * 0.5000 * 13168.9 = 6584.43 lb.

Distribute the Base shear force to each element according tothe equations Fx = Cvx * V (eqn. 9.2.3.4-1 ) and the verticaldistribution factor Cvx = Wx*hx^(k)/( Sum of Wi*hi^(k) ) and k isan exponent which is related to the period of Vibration.In this case, the value of k was 1.0000 .

Reinforcement CALCULATION, Description: NOZZLE 2168










These Results are for the Internal Pressure Case :

Ratio of tn/t = ( 3.000 - 0.062 ) / ( 0.750 - 0.062 ) = 4.273

The value of B1 is 54.0 and the value of B2 is 318.0

The mean Vessel Dia. Dm is 44.812 and the mean conn. pipe Dia. is 8.188

The Diameter ratio Dmrat is dm/Dm is 8.188 /44.812 = 0.183

Lamda = Dmrat*( Dm/t ) = 0.183 * sqrt( 44.812 /0.688 ) = 1.475

Check Equation (1):

= [2+2*Dmrat^1.5*(tn/t)½+1.25*Lamda]/[1+(Dmrat)½*(tn/t)^(1.5)] = [2 + 2*0.183^1.5 * ( 3.000 /0.750 )½ + 1.25 * 1.475 ] / [1 + (0.183 )½ * (3.000 /0.750 )^(1.5)] = 0.873


To pass check (1) 0.873 must be <= 2.95( t/tr ) which is 3.990

Check Equation (2):

= ([B1(tn/t)²+228(tn/t)(Dmrat)+B2]Lamda+155)/ [108Lamda²+[228(Dmrat)²]Lamda+152] = ([54.000 *(4.273 )²+228*(4.273 )*(0.183 )+318.0 ]1.475 +155)/ [108*1.475² + (228 * Dmrat² + 228)*0.183 + 152] = 3.187

To pass check (2) 3.187 must be >= (0.93+0.005*Lamda)(tr/t) which is 0.6

This connection passes checks (1) and (2), as such the internalpressure calculations per UG-37 are not required. Please insurethis connection meets the following criteria :

1 - Cyclic loading is not a controlling design requirement.2 - The opening is > 1.8(Dm*t)½ from any structural discontinuity.3 - The nozzle spacing is greater than 3 times their average diameter.4 - The opening is circular in cross section and is normal to the vessel.5 - The vessel is not operating in the creep range.6 - The ratio of Yield Strenth to Tensile Strength must be <= 0.80.


These Results are for the MAP(nc) Pressure Case :

Ratio of tn/t = ( 3.000 - 0.000 ) / ( 0.750 - 0.000 ) = 4.000

The value of B1 is 54.0 and the value of B2 is 318.0

The mean Vessel Dia. Dm is 44.750 and the mean conn. pipe Dia. is 8.125

The Diameter ratio Dmrat is dm/Dm is 8.125 /44.750 = 0.182

Lamda = Dmrat*( Dm/t ) = 0.182 * sqrt( 44.750 /0.750 ) = 1.402

Check Equation (1):

= [2+2*Dmrat^1.5*(tn/t)½+1.25*Lamda]/[1+(Dmrat)½*(tn/t)^(1.5)] = [2 + 2*0.182^1.5 * ( 3.000 /0.750 )½ + 1.25 * 1.402 ] / [1 + (0.182 )½ * (3.000 /0.750 )^(1.5)] = 0.921

To pass check (1) 0.921 must be <= 2.95( t/tr ) which is 3.892

Check Equation (2):

= ([B1(tn/t)²+228(tn/t)(Dmrat)+B2]Lamda+155)/ [108Lamda²+[228(Dmrat)²]Lamda+152] = ([54.000 *(4.000 )²+228*(4.000 )*(0.182 )+318.0 ]1.402 +155)/ [108*1.402² + (228 * Dmrat² + 228)*0.182 + 152] = 2.944

To pass check (2) 2.944 must be >= (0.93+0.005*Lamda)(tr/t) which is 0.7

This connection passes checks (1) and (2), as such the internalpressure calculations per UG-37 are not required. Please insurethis connection meets the following criteria :

1 - Cyclic loading is not a controlling design requirement.2 - The opening is > 1.8(Dm*t)½ from any structural discontinuity.


3 - The nozzle spacing is greater than 3 times their average diameter.4 - The opening is circular in cross section and is normal to the vessel.5 - The vessel is not operating in the creep range.6 - The ratio of Yield Strenth to Tensile Strength must be <= 0.80.
