Wind Load Calculation : Step: 8 11:07a Jan 30,2014

Input Values:
















Wind Analysis Results

Static Gust-Effect Factor, Operating Case [G]:

= min(0.85, 0.925((1 + 1.7 * gQ * Izbar * Q )/( 1 + 1.7 * gV * Izbar)))

= min(0.85,0.925((1+1.7*3.400*0.228*0.958)/(1+1.7*3.400*0.228)))

= min(0.85, 0.903 )

= 0.850

Natural Frequency of Vessel (Operating) 47.417 Hz

Natural Frequency of Vessel (Empty) 47.417 Hz

Natural Frequency of Vessel (Test) 41.415 Hz

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

Force Coefficient [Cf] 0.507

Structure Height to Diameter ratio 1.419

Height to top of Structure 3305.500 mm

This is classified as a rigid structure. Static analysis performed.

Sample Calculation for the First Element

The ASCE code performs all calculations in Imperial Units

only. The wind pressure is therefore computed in these units.

Value of [Alpha] and [Zg]:

Exposure Category: C from Table C6-2

Alpha = 9.500 : Zg = 274320.000 mm

Effective Height [z]:

= Centroid Height + Vessel Base Elevation

= 425.000 + 19663.998 = 20088.998 mm




= 65.909 ft. Imperial Units

Velocity Pressure coefficient evaluated at height z [Kz]:

Because z (65.909 ft.) > 15 ft.

= 2.01 * ( z / Zg ) ^(2 / Alpha)

= 2.01 * ( 65.909/900.000 )^(2/9.500 )

= 1.159

Type of Hill: No Hill

Wind Directionality Factor [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 )

= ( 1 + 0.000 * 0.000 * 0.000 )

= 1.0000

Velocity Pressure evaluated at height z, Imperial Units [qz]:

= 0.00256 * Kz * Kzt * Kd * I * Vr(mph)

= 0.00256 * 1.159 * 1.000 * 0.950 * 1.150 * 97.085

= 30.6 psf [1463.182 ] N/m

Force on the first element [F]:

= qz * G * Cf * WindArea

= 30.560 * 0.850 * 0.507 * 27.097

= 356.8 lbs. [1587.2 ] N

L - Total height of structure mm




Lc - Total length of conical section(s) of vessel mm

tb - Uncorroded plate thickness at bottom of vessel mm

V30 - Design Wind Speed provided by user m/sec

Vc - Critical wind velocity m/sec

Vw - Maximum wind speed at top of structure m/sec

W - Total corroded weight of structure N

Ws - Cor. vessel weight excl. weight of parts which do not effect stiff. N

Z - Maximum amplitude of vibration at top of vessel mm

Dl - Logarithmic decrement ( taken as 0.03 for Welded Structures )

Vp - Vib. Chance, 0.393E-05 no chance. [Vp]:

= W / ( L * Dr)

= 170762/( 2680.00 * 2436.000 )

= 0.10738E-04

Since Vp is > 0.393E-05 no further vibration analysis is required !

Rw1 = 135.000 , Rw2 = 105.470 mm

Calculation of required Basering Thickness, (Simplified) [Tb]:

Allowable Bending Stress 1.5 Basope = 2068.500 bar

= Max(Rw1,Rw2) * ( 3 * Sc / S ) + CA per Jawad & Farr Eq. 12.12

= Max(135.0000 ,105.4700 ) * ( 3 * 22.482/2068.500 ) + 0.0000

= 24.3774 mm

Basering Stress at given Thickness [Sb]

= 3 * Sc * ( Max[Rw1, Rw2]/(Tb - Ca) )

= 3 * 22.482 * ( Max[135.000 , 105.470 ]/(28.580 - 0.000 ) )

= 1504.892 , must be less than 2068.500 bar

Required Thickness of Top Plate in Tension:

(Calculated as a fixed beam per Megyesy)

Ft = (Sa*Abss), Bolt Allowable Stress * Area

Rm = (Ft * 2 * Cg)/8, Bending Moment

Sb Allowable Bending Stress

Wt = (Topwth - Bnd), Width of Section

T = ( 6 * Rm / ( Sb * Wt )) + CA

T = ( 6 * 2459/( 2068 * 86.9000 )) + 0.0000

T = 28.6472 mm




Required Thickness of Continuous Top Ring per Moss:

a = ( Dc-SkirtOD )/2 Skirt Distance to Bolt Circle

P = Sa*Abss Bolt Allowable Stress * Area

l = Avgwdt Average Gusset Width

g1 = Gamma 1 Constant Term f( b/l )

g2 = Gamma 2 Constant Term f( b/l )

g = Flat distance / 2 Nut 1/2 Dimension (from Tema)

Fb = Allowable Bending Stress

Mo = P/(4pi)[1.3(ln((2lsin(pia/l)/(pig)))+1]-[(0.7-g2)P/(4pi)] Moment Term

Tc = ( 6 * Abs(Mo) / Fb ) + CA Required Thickness

Tc = ( 6 * 844/2068 ) + 0.000

Weld Size Calculations per Steel Plate Engineering Data - Vol. 2

Compute the Weld load at the Skirt/Base Junction [W]

= SkirtStress * ( SkirtThickness - CA )

= 35.108 * ( 9.530 - 0.000 )

= 33.46 N/mm

Results for Computed Minimum Basering Weld Size [BWeld]

= W / [( 0.4 * Yield ) * 2 * 0.707]

= 33/[( 0.4 * 2493 ) * 2 * 0.707]

= 0.237 mm




Results for Computed Minimum Gusset and Top Plate to Skirt Weld Size

Vertical Plate Load [Wv]

= Bolt Load / ( Cmwth + 2 * ( Hg + Tta ) )

= 258786.6/( 107.760 + 2 * ( 221.400 + 31.750 ) )

= 421.435 N/mm

Horizontal Plate Load [Wh]

= Bolt Load * e / ( Cmwth * (Hg+Tta) + 0.6667 * (Hg+Tta) )

= 258786.6 * 65.000/(107.760 * (253.150 ) + 0.6667 * (253.150 ) )

= 240.291 N/mm

Resultant Weld Load [Wr]

= ( Wv + Wh)

= ( 421.44 + 240.29)

= 485.126 N/mm

Results for Computed Min Gusset and Top Plate to Skirt Weld Size [GsWeld]

= Wr / [( 0.4 * Yield ) * 2 * 0.707]

= 485.13/[( 0.4 * 2493 ) * 2 * 0.707]

= 3.440 mm

Results for Computed Minimum Gusset to Top Plate Weld Size

Weld Load [Wv]

= Bolt Load / ( 2 * TopWth )

= 258786.6/( 2 * 125.000 )

= 1035.146 N/mm

Weld Load [Wh]

= Bolt Load * e / ( 2 * Hgt * TopWth )

= 258786.6 * 65.00/( 2 * 253.150 * 125.000 )

= 265.789 N/mm

Resultant Weld Load [Wr]

= ( Wv + Wh)

= ( 1035.15 + 265.79)

= 1068.724 N/mm

Results for Computed Min Gusset to Top Plate Weld Size [GtpWeld]

= Wr / [( 0.4 * Yield ) * 2 * 0.707]

= 1068.72/[( 0.4 * 2493 ) * 2 * 0.707]

= 7.579 mm

Note: The calculated weld sizes need not exceed the component thickness

framing into the weld. At the same time, the weld must meet a minimum size

specification which is 3/16 in. (4.76 mm) or 1/4 in. (6.35 mm), depending

on the component thickness.
