The Natural Frequencies for the vessel have been computed iteratively

by solving a system of matrices. These matrices describe the mass

Wind Analysis Results

Wind Load Results per ASCE-7 98/02/05:

Note: Per Section 1609 of IBC 2003/06 these results are also applicable

for the determination of Wind Loads on structures (1609.1.1).

User Entered Importance Factor is 1.000

Gust Effect Factor (Ope)(G or Gf) 0.800

User entered Beta Value ( Operating Case ) 0.0100

Shape Factor (Cf) 0.528

User Entered Basic Wind Speed 40.0 m/sec

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 = 2 (B) thus from Table C6-2:

Alpha = 7.000 : Zg = 365760.000 mm.

Effective Height [z]

= Centroid Hgt. + Vessel Base Elevation

= 83.336 + 0.000 = 83.336 mm.

= 0.273 ft. Imperial Units

Compute [Kz]

Because z (0.273 ft.) < 15 ft.

= 2.01 * ( 15 / Zg ) 2 / Alpha


48

= 2.01 * ( 15 / 1200.000 )2 / 7.000

= 0.575

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 )

= ( 1 + 0.000 * 0.000 * 0.000 )

= 1.0000

Basic Wind Pressure, Imperial Units [qz]:

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

= 0.00256 * 0.575 * 1.000 * 0.950 * 1.000 * 89.479

= 11.191 psf [535.811 ] N./m

Force on the first element [F]:

Vp - Vib. Chance,


50

0.000 / 897.750 = 0.000

#2 - ( D / L ) * 104 < 8.0 (English Units)

- ( 1.11 / 2.95 ) * 104 = 1275.874 [Geometry Violation]

Compute the vibration possibility. If Vp > 0.393E-05 no chance. [Vp]:

= W / ( L * Dr)

= 1703 / ( 897.75 * 324.923 )

= 0.000

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

The UBC Zone Factor for the Vessel is ............. 0.2000

The Importance Factor as Specified by the User is . 1.250

The UBC Seismic Coefficient Value Ca is ........... 0.360

The UBC Seismic Coefficient Value Cv is ........... 0.840

Note: The base shear and top load printed above have been modified

by the user defined Earthquake scalar.

Calculation Steps for Computing the design Base Shear (V) per UBC 1997

Computation of V per equation (34-1):

V = 0.7 * Ca * I * W

V = 0.7 * 0.360 * 1.250 * 1731

V = 545.4 N.

Computation of V per equation (30-5):

V = 2.5 * Ca * I * W / R

V = 2.5 * 0.360 * 1.25 * 1731 / 2.000

V = 973.9 N.

The computed base shear is the minimum of V from 34-1 and 30-5.


52

Computation of V per equation (34-2), minimum V. V cannot be less than

this value !

V = 0.56 * Ca * I * W

V = 0.56 * 0.360 * 1.250 * 1731

V = 436.3 N.

Total Adjusted Base Shear V:

= V * Scalar Multiplier = 545.4 * 0.7143 = 389.6 N.

Next compute the top load per equation 30-14. The top load is

zero if the period of vibration (T) is less than 0.7 seconds.

Note: This value does not need to exceed 0.25V.

Ft = Min( 0.07 * T * V, 0.25 * V )

Ft = Min( 0.07 * 0.029 * 545 , 0.25 * 545 )

Ft = 0.0 N.

Next Sum the earthquake weights times their heights (wi*hi):

Current Sum = Prev. Sum + Wght 517. * Hght -104.000 = -54.

Current Sum = Prev. Sum + Wght -316. * Hght -19.000 = -48.

Current Sum = Prev. Sum + Wght 509. * Hght 409.000 = 160.



Compute the load at each level based on equation 30-15 and multiply

by the load case scalar. The sum will be the total adjusted shear.

Fx = (( V - Ft ) * wx * hx / ( sum of ( wi * hi ))) * EqFact

Fx = [(545.) * 517. * -104.000 / 1032.]*0.7143 = -20.

Fx = [(545.) * -316. * -19.000 / 1032.]*0.7143 = 2.


53

Fx = [(545.) * 509. * 409.000 / 1032.]*0.7143 = 79.

Fx = [(545.) * 409. * 809.000 / 1032.]*0.7143 = 125.

Fx = [(545.) * 613. * 881.875 / 1032.]*0.7143 = 204.
