Soil SpecificationBearing capacity :-0.9 Kg/Cm²2 Kg/Cm²3.5 Kg/Cm²Dead loadingThe self-weight of towers including ladders and platforms is based on nominal sizes of members with an appropriate allowance for gussets, bolts and welds.Wind LoadingTwo basic types of towers may be considered and this isA) "heavy" range.The heavy range should be designed for a basic wind speed of 41,666 m/s at an altitude of 150m. This data is preliminary and may be altered as soon as more accurate wind information data will be available.Live LoadIndividual members with an angle of 30º to the horizontal or less shall be designed to support a 1.5kNvertical point load at mid span.Towers shall be designed as Class "II" structures - exposure category "D" - topographic category (3) according to ANSI/TIA/EIA-222-G or equivalent by in BS 8100: Part 1: 1986; Figure 2.1. (Range between?(300 and 700) meters ) .The serviceability check of the towers will be carried out in accordance with BS 8100 clause 3.3. Or equivalent by ANSI/TIA/EIA-222-GThe rotational displacement for any tower structure shall be limited to 0.5º measured at the highest dish level.SteelworkThe plan shape of tower is squareFor lattice towers all steelwork including angles, flats and round solid bars will be hot rolled Grade S275 or S355 to BS EN 10 025. Also steelwork circular hollow sections will be hot rolled S275 or S355 to BS EN 10 210.Bolts will be hot dip galvanized in accordance with BS 7371: Part 6: 1998.The work plats should distribution on height of tower each 10m, except the end work pleat should put on distance 3m from the top of tower.Antenna supportsEach tower need the number of antenna supports as following:-1- GSM antenna . . . . . . . . . . . . . . . . . . . . . . . 6 pieces2- Microwave antenna . . . . . . . . . . . . . . . . . . 8 piecesConcrete workThe concrete work should be designed by ACI-318M-05 requirements. Take care for following designcriteria:-1- Concrete strength Fc/28days 21 MPa2- Reinforcement strength Fy 280 MPa3- The maximum bars size which use in design reinforcement concrete is 20mm. (Diameter of bar)Access & ClimbingAll base station towers shall be fitted with a access ladder in part complying with BS 4211. The access system shall also comprise a GlideLock/RailLock or similar approved system. Sufficient work platforms shall be provided each 10m height of tower.Design lifeTower structures:Minimum structural Design Life shall be 30 years.Coating (Thickness of zinc)Coating should not less 100 μm according ASTM A123 / A123M ( Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products ).ICAO standardCodas and StandardsBritish Standards/ Code of Practice and Euro standards or find the equivalent which is recommended by ANSI/TIA/EIA 222-G.BS 648 Schedule of weights of building materialsBS 4211 Specification for ladders for permanent access to chimneys, otherhigh structures, silos & bins.BS 4395 Specification for high strength friction grip bolts & associated nuts& washers for structural engineering.
