Wind load calculation of parabolic antenna : Fa = Ca . A . Kz . GH . V2 Fs = Cs . A . Kz . GH . V2 M = Cm . D . A . Kz . GH . V2 Ha = v ( Fa2 + Fs2 ) Mt = Fa . X + Fs . Y + M. Where : Fa = Axial Force ( lb ) Fs = Side Force ( lb ) M = Twisting Moment ( ft-lb ) Ca = Wind Load Coefficient Cs = Wind Load Coefficient Cm = Wind Load Coefficient Ha = Wind load antenna ( lb ) Mt = Total twisting moment ( ft-lb ) V

= Wind Velocity ( mph )

A

= Normal projected area of antenna (ft2 )

D

= Antenna diameter ( ft )

X

= The offset of the mounting pipe ( ft )

Y

= The distance on the reflector axis from the reflector vertex to the center of the mounting pipe ( ft )

c. Load Combination According to EIA Standard EIA – 222 – F, only the following load combination shall be investigated when calculating the maximum member stresses and structure reactions :

D1 + Wo Where : D1 = Dead weight of the structure and appurtenances Wo = Design wind load on the structure, appurtenances, etc. 3. Properties of Loading $name type $

Where : name

: Name by which the antenna is referenced in the TWR file.

coeff

: Name of set of coefficients to be used in calculating the projected area and wind resistance of the antenna.

Note : Bolt JIS grade 8.8 is equivalent to ASTM A325. E. STRUCTURAL ANALYSIS Three dimensional structure analysis should be applied to determine tower member stresses. The analysis is carried out by computer program on the basis of a valid stress analysis program. Moment of inertia is reduced with 0.1 factor since the tower is design is based on the axial analysis. F. OPERATIONAL CONDITION Maximum twist and sway is 1 degree at 80 km/hour operational wind velocity, maximum vertical displacement H/1000, and maximum horizontal displacement H/200, where H is height tower.
