Engineered – Heavy Wind Loads Extend to over 100ft. 3.7 shows a communication tower constructed in Japan in the 1970s. Fig. The percentage of openings in towers structure will be more than 30%, so wind loads acting on the tower will be of less. Wind loads for screened enclosures shall be determined in accordance with Section 2002.4 communications equipment used to receive and/or transmit electron magnetic waves. The best protection against icing is a well-constructed tower built to withstand ice loads for locations where ice accumulations are known to occur. For the wind and ice analysis it was determined that the bracing on the tower controls the structural integrity of the tower. Retrofit work for a Communication Tower The BRB system is also used to retrofit truss structures. Yes No 2. Risk categorization established ed in the derivation of design loads for flood, wind, snow, earthquake, and ice applied to the structure during design and analysis.
